Changelog

New

1️⃣ action-sheet dialog

We've implemented a range slider to easily adjust the size of the dialog using only a keyboard, enhancing accessibility. We've used a similar approach for our SplitPageLayout resizer. I've also implemented reduced-motion support.

2️⃣ full-screen dialog

This is quite simple, as it closely resembles the existing dialog behavior, with the only difference being that it's full-screen.

Changed

• Storybook features always display dialogs in an open state so that snapshots can effectively capture any changes.
• Removed the ability to change props in features for simplicity and consistency with other components
• In the example called 'WithCustomRenderers', I've placed the header, content, and footer components inside the 'WithCustomRenderers' component. This change improves readability, especially when highlighting the code.

Removed

It's looking good! Just one little thing we might to address: we don't delay calling onClose when clicking the "x" or keying Esc

If this is intentional, don't worry about it.

[mperrotti]

If this merges before #4048, I mighjt update my PR to move these tests into the same test file.

[maximedegreve]

Yeah that was intentionally because I thought you aren't swiping it away.

Looking good. Since this is such a big PR, it might be nice to get a review from somebody who's "officially" and engineer before merging. Not required though 🙂
