fix(formulus): Limiting keyboard re-popping up during text editing

[r0ssing]

Fix IME keyboard behaviour

Description

Sometimes the formplayer will resize when the IME keyboard is popping up. This has largely been resolved, however sometimes it still occurs when changing a value due to timing issues. This PR tries to counter-act that behaviour to make the UX more pleasant.
