Enable space bar trackpad/swipe delete on emoji/clipboard screens

Is your feature request related to a problem? Please describe.

Space bar and delete swiping doesn't work on emoji and clipboard screens.

Describe the solution you'd like

Would be nice if it worked the same as on the keyboard screen, e.g. being able to move in text/swipe delete even when emoji or clipboard screens are open.

Additional context

This is the case with the og OpenBoard, but considering development of that version seems to have stalled, this would be a nice addition.

Currently the keys at the bottom of emoji and clipboard views are "just buttons", so the PointerTracker used for handling the swipe for keyboards does not work properly (it does something, but cannot find the correct keys).

Implementing an actual KeyboardView instead of the buttons would be the most important step towards solving this.

I would love seeing this implemented. I love the "move_cursor" swipe.

I have to close the emoji view to be able to move the cursor, then go back to emoji view to add one more.
