@puneetlath, @fedirjh Whoops! This issue is 2 days overdue. Let's get this updated quick!

[charles-liang]

@kavimuru can you provide your android and chrome version? I tried to replicate it, but it didn't occur.
I run in

Chrome 113
Android 14

[puneetlath]

Are you able to repro @fedirjh?

[fedirjh]

Are you able to repro @fedirjh?

@puneetlath I can reproduce with these steps:

1. Go to https://staging.new.expensify.com/
2. Tap the email field
3. Enter a very long email
4. Double-tap the email to select it

@kavimuru Can you test with these steps and see if you can reproduce the same issue?

Proposal

Please re-state the problem that we are trying to solve in this issue.

Login - mweb - Login screen gets off center after selecting saved credentials

What is the root cause of that problem?

When the SVG uses absolute positioning and is either large in size or positioned such that part of it extends outside the viewport, this might lead to the appearance of scrollbars because the browser needs to provide a way for users to access and view the overflowed part.

If switch to fixed positioning, the SVG will be positioned relative to the viewport and will be independent of the rest of the document's layout or scroll. Therefore, the SVG's size or position will not affect the document's scroll behavior.

App/src/pages/signin/SignInPageLayout/index.tsx

Line 148 in 915a1b6

<View style={[styles.pAbsolute, styles.w100, StyleUtils.getHeight(backgroundImageHeight), StyleUtils.getBackgroundColorStyle(theme.highlightBG)]}>

What changes do you th

ink we should make in order to solve the problem?

Proposal

Please re-state the problem that we are trying to solve in this issue.

Login - mweb - Login screen gets off center when selecting all text content with dblclick

What is the root cause of that problem?

We are using an overflowHidden to wrap the SignInPageContent (The overflow: hidden CSS property on a parent component can clip any content that overflows its boundaries. This can affect how child components (like a TextInput) are displayed, especially when they extend beyond the parent's visible area due to text selection handles), when we select all the input content there is a moment where the magnfier (in android) try to adjust to the space available and we get the error / weird behavior.

What changes do you think we should make in order to solve the problem?

We can remove the overflowHidden for the rest of navigators/devices and let it in Safari when mobile (due the bug there is because the magnifier behavior) in the View component inside SignInPageLayout:
<View style={[ styles.flex1, styles.flexColumn, **Browser.isMobileSafari() ? styles.overflowHidden : {},** StyleUtils.getMinimumHeight(backgroundImageHeight), StyleUtils.getSignInBgStyles(theme), ]} >

📣 It's been a week! Do we have any satisfactory proposals yet? Do we need to adjust the bounty for this issue? 💸

[fedirjh]

@charles-liang Your root cause analysis is not clear to me. It does not explain why this issue occurs when the input text is long.

[fedirjh]

@samilabud It seems overflowHidden style was implemented in this PR #25457 to fix another issue (#24328). Is it safe to remove this style? Won’t the old bug reappear?

Hi @fedirjh, you were right, I have updated my proposal, I have included new video with evidence, here below what was happening with my previous proposal (was working for mobile chrome only):

[charles-liang]

@fedirjh

@charles-liang Your root cause analysis is not clear to me. It does not explain why this issue occurs when the input text is long.

I understand that removing overflow: hidden might cause other issues, which is why I didn’t propose it.
Since position: absolute can expand the page and make this section scrollable, it’s only because overflow: hidden hides the scrollbar that users can't scroll, but it doesn’t prevent scrolling programmatically.
On Android mobile web, when a toolbar pops up, the system will position the menu to the right of the last character of the text if the right side can scroll, which would cause the page to scroll. If it can't scroll, it will shift to the left. That's why this issue only appears on Android’s mobile web.

The longtext does not need to be very long; it only needs to exceed the length of the input box by a few characters, depending on the width of the whitespace to the right of the input box.

On the other hand, position: fixed doesn’t expand the page and prevents scrolling.

If this makes it clearer for you, I will update my proposal.

[puneetlath]

@fedirjh how's this going?

[fedirjh]

@charles-liang Thanks for the update. However, I am leaning toward @samilabud solution. I believe that removing the style causing the issue (overflowHidden) and applying it selectively to mWeb Safari would be the most effective approach.

[fedirjh]

Let's proceed with @samilabud's Proposal.

Thanks @fedirjh, I have created the PR, just waiting for the upwork offer.

Anything else I'm at your service!

[puneetlath]

Sorry, just for my understanding, does Safari treat overflow:hidden different than Chrome?

[samilabud]

Sorry, just for my understanding, does Safari treat overflow:hidden different than Chrome?

Not really, the problem with Safari is that it has a magnifying glass that affects the CSS and in this case makes the content move as if it had a scroll (even with the overflow hidden).
