[LH3471] Glitchy tooltip when hovering over word count in Composition mode.

In composition mode, mousing over the panel at the bottom causes the tooltip to flash whenever the mouse stops moving (or something like that). It’s inconsistent and very visually distracting.

Here’s a GIF of the bug in action:
