This issue is meant to keep track of the multiple bugs that are specific to WebKit, that were resolved, but that may benefit from additional debugging, especially as we may not have minimal reproductible testcases for some of them.
iOS Patch
To sum things up, on rotate to landscape in scroll on iOS, the text-adjustment algorithm is mapping 100%, 1rem, etc. to 25px when it is set to 16px. It will never go back to its original value and will also counteracts any zoom value applied (so 25px can become 31.25px if a zoom value of 80% is applied, etc.).
We do not know the root cause of the issue, therefore do not have a minimum reproductible test case.
iPadOS Patch
On iPadOS, there is a specific issue when the website is required as desktop (which is the default). With zoom interventions creating nasty rendering issues when text is styled (e.g. font-style, font-variant, etc.)
Scroll is not scrollable
In Webkit, scroll mode is not scrollable until there is a recalc/reflow happening. We consequently have to force a recalc. This issue was previously resolved as a side effect of adding custom properties after load, or injecting elements in the DOM (scroll affordances).
We do not know the root cause of the issue, therefore do not have a minimum reproductible test case.
