Update Safari + iOS data for optgroup.disabled
Summary
Record incomplete support for the disabled attribute on optgroup elements in desktop Safari v6 and current versions of iOS Safari.
Test results and supporting details
@caugner created a JS Bin test case and was able to reproduce back to iOS 11.2.
I tested in:
- Safari 17.6 on MacOS 12.7.6 - passes
- Safari 18.4 on MacOS 15.4.1 - passes
- iOS 18.3.1 - fails
Commit history found from bug 87614 suggests this issue was likely present in desktop Safari 6 (introduced in 536.11), but fixed by version 7 (fix merged in 537.43.1). I'm unable to test whether it was actually working properly earlier.
There is an unresolved bug for iOS and iPadOS.
