Indicate pressed character via a small popover just above the hit key.
Similar to what osk-sdl does it makes it more visible what was typed when looking at the osk (rather than the TextEntry) and would help https://source.puri.sm/Librem5/squeekboard/-/issues/281 since the same popover could indicate the alternate key before releasing.
See https://fosstodon.org/@postmarketOS/105397265991389371 how this looks in osk-sdl.
