Steps to reproduce:

1. Visit <https://unixpapa.com/js/testkey.html>

If you have a build with the fix for bug #199257 then:
2. Ensure default handling of keypress is suppressed.
3. Press Command + A

2. Press some keys, like a, b, c.
3. Ensure default handling of keypress is suppressed.
4. Focus the text field.
5. Press Command + A

Then the content of the page (if you have the fix for bug #199257) or briefly the contents of the field will be selected. But Command + A should have been selected. Compare to Mac.

Note, Command + A can be prevented from keydown on iOS.
