I can see only native menu on long touch, the backwards-P toolbar has no undo/redo buttons:

I'd move the undo/redo buttons from selection toolbar to the block toolbar which is always visible

It may be a good idea. But... then we violate the "block" thing in "block toolbar" cause undo/redo are just generic buttons.

It's also a part of bigger issue with contentEditable that we cannot listen to the native undo/redo: w3c/editing#150

It does not feel like a big issue to me moving those buttons to the block toolbar. Sooner or later other buttons not quite related to block will need to land there, like, for instance, track changes controls.

A serious question - do I need a device with Android to reproduce this issue?

[Reinmar]

I think the same issue is reproducible on iOS. The only requirement is the lack of hardware keyboard.
