Update compat data for PromiseRejectionEvent

[TrevorBurnham]

Follow-up for #2100

Currently, the MDN docs indicate that PromiseRejectionEvent and the associated window.onunhandledrejection and window.onrejectionhandled properties are Chrome-only. I believe the CanIUse data for these events are correct: https://caniuse.com/#feat=unhandledrejection

Also, I believe this same data should appear on https://developer.mozilla.org/en-US/docs/Web/Events/unhandledrejection#Browser_compatibility.

Hi @TrevorBurnham, thank you for this PR and welcome to BCD. A few changes to suggest on this one—we can get the data accuracy a little better I think—but this is a great start. Thank you again!

@ddbeck OK, I think I've addressed all of your feedback.

Regarding safari_ios: Looking at iOS devices in BrowserStack, I can confirm that onunhandledrejection is supported in iOS 12.0.0. Support was likely introduced in an earlier iOS 11.x release (Caniuse says 11.4), but I can't pin that version down. Would it be better to set "version_added": "12.0.0" instead of "version_added": null?

@TrevorBurnham, welcome to BCD and thank you for doing this.

FYI, caniuse and Chrome Status are fine as sources if you don't have anything better. Be aware that they are second-hand sources.

Here's a search result on the commit hash from a Chromium system called Omaha Proxy. The link on that result takes you to the actual commit where the feature landed. I got the commit hash from the IDL's file history

OK, them I'm going to go with 11.4 as the safari_ios version, per caniuse. I've added that version to safari_ios.json to satisfy the linter: 0f84926

Feedback fixed; new review needed for browser changes

@Elchi3 would you mind reviewing the browser change here? I don't feel confident about reviewing safari_ios.json additions myself

[Elchi3]

hm, I have no idea whether or not these are versions that we would care about, or just minor updates without feature changes. Does anyone have Safari release notes handy? We need to find out which of the 11.x releases are major releases with web platform feature changes.

Caniuse seems to have some grouping:
"11.0-11.2"
"11.3-11.4"
For us this would mean we would add only add 11.0 and 11.3, but we've already added 11.1...

This is also related to #2006.

[TrevorBurnham]

@vinyldarkscratch Per your comment, I've changed the iOS version specified here from "11.4" to to "11.3" and rebased against master.

Let me know if any other changes are needed here.

Awesome, thanks for the update, and thank you for the updates! Since this no longer makes any changes to the browsers, I think that this is ready.

@ddbeck Since you know much more about this PR than I do (and the PR looks great to me), want to give it one final review?

👍

[ddbeck]

Thank you so much, @TrevorBurnham! This was one of the longer-lived PRs in BCD, so I really appreciate your patience on this. Let's merge this! 🎉
