[I'm spinning this off from https://github.com/mozilla-mobile/fenix/issues/2038 for a part of the original report there that @VitasLoWang just pointed out is still broken.]
tl;dr: Normally when you double-tap a word in Fenix, that word gets selected. But in a textarea, double-tapping does not cause the word to be selected.
- Load the attached testcase.
- Double-tap a word in the textarea.
The word should be selected.
No text is selected; instead, the caret moves and the context-menu appears. (The first tap places the caret and the second tap pops up the context-menu, I think?)
For comparison: if you double-tap a word in the regular div (outside of the textarea), then it does get selected. So this double-tap-to-select is indeed a gesture that we have implemented; it just doesn't work in textareas (or editable fields in general, probably).
I'm using a Google Pixel 6a with Android 13.
Firefox Nightly 110 gives ACTUAL RESULTS (and it seems versions at least as far back as 2019 did as well, per https://github.com/mozilla-mobile/fenix/issues/2038#issue-437315539 )
Chrome 108 gives EXPECTED RESULTS.
