TextBox text selection/copy doesn't work

[LyleRolleman-plst]

Usage Information

3.6.0

Description

Trying to select text within a TextBox doesn't work properly on Android/iOS. Tapping and holding brings up a Cut, Copy, Paste and Select All context menu, but cut and copy remain disabled with no ability to select the text, except Select All which then hides the context menu, making it pretty useless.

This isn't a problem when using the default FluentTheme so something in here seems to be overriding and breaking the behaviour

Reproduction Steps

Attempt to select TextBox with text using usual tap/hold/drag. Observe doesn't select, with aforementioned broken context menu. Drag handles from base Avalonia/FluentTheme do not appear

Expected Behavior

I should be able to select text in a TextBox to copy

Actual Behavior

See description

Seems like Material textbox behaves as default Fluent one. Here is the demo:

I've also doesn't see any drag handles from avalonia. May be I'm missing something? Can you share the sample app with proper avalonia's TextBox behavior?

I've attached two screenshots that show the difference between Material and Fluent (the theme being the only difference between the projects)

I've also attached the test project.

Oh, probably the 11.1.0-beta2 is the reason. I'll take a look.

Seems like this is exclusive 11.1.0-beta feature and wasn't accessible within 11.0.*.
So, probably I've should start a new branch to target new avalonia version.

That would certainly be welcome as we do need the beta branch features and I get the impression the beta will be moving into general release very soon
