[jmartinesp]

Type of change

• Feature
• Bugfix
• Technical
• Other :

Content

• Hides the container for the rich text menu instead of the rich text menu instead. This should prevent the invisible HorizontalScrollView from overlapping with the EditText and intercepting touch events.
• Also removes a minHeight value from styles that's no longer needed.

Motivation and context

Fixes #7801 .

Tests

• Enable the Rich Text Editor in Settings > Labs.
• Open a room.
• Tap on the + icon, disable 'Text formatting' option at the bottom.
• Write some text (it's even better if it has several lines) and then try to select any point of it.

Tested devices

• Physical
• Emulator
• OS version(s): 13
