Keyboard trackpad right click doesn't work

Testing version:
iPadOS 2.0.2

What were you doing:
Right clicking selected test

What feature did you use:
Right click

What happened:
Right clicking selected text with trackpad causes the menu to appear momentarily, and then disappear. Same happens if you select text with your finger, and click say “replace” to correct a misspelling.

What did you expect to happen:
The menu to stay visible until used

Demo (comparing first finger-based select + menu, then keyboard based):

Follow up - this doesn’t apply to files (like an MP3 attachment for example) which can be right-clicked successfully

Still same problem after update
