expanding text selection on iOS does not behave the same as native

[jyn514]

in the attached video, i do the following things:

1. double-tap on a word to select it
2. drag on the message boundary indicators to expand the selection
3. drag on the right side of the word.

in every iOS app i've tried other than zulip-flutter, step 3 results in expanding the selection. in zulip, it makes the boundary indicators disappear altogether instead.

Thanks for the report. This sounds like almost certainly a bug in Flutter upstream.

I just spent a few minutes searching the Flutter issue tracker and didn't find an existing upstream issue for this. So the next step for us will be to file one, starting by reproducing the issue in a tiny Flutter app.

We're focused right now on getting the new app out to all our users in a few weeks, and I think this is an issue for after that launch. I'll label this to make sure that we see it in the weeks after launch when we're triaging which issues to work on next.
