Test case for the bug

Webkit clips the rendered text, when using the extrabold weight of the Syne webfont from Google Fonts.

Attached test case demonstrates the issue.

The same text is rendered correctly in Chrome 108 and Firefox 108.

I can't seem to reproduce this clipping issue.

Cool, let me check STP.

I am seeing it now. For some reason I had "full page accelerated drawing" disabled (which makes the bug go away).

The cause of this bug was outside of WebKit, so resolving as MOVED.

The fix for this issue shipped as part of iOS 16.4.1 and macOS 13.3.1.
