TextEdit with autowrap and fit content height does not work correctly

Issue description

When you set TextEdit's wrap mode to boundary and enable scroll_fit_content_height, the TextEdit is expected to never show scrollbars. But it does show scrollbars at certain sizes, both horizontal and vertical.

I remember this worked seamlessly when the fit content feature was first added.

Moreover, if the text is sufficiently long, it can freeze at certain sizes.

(also notice how horizontal scroll appears despite using autowrap)

EDIT:
Seems like #80546 covers the freeze (crash) part. But the scrollbar bug is still relevant here.

Steps to reproduce

1. Add TextEdit
2. Set wrap_mode to Boundary
3. Enable scroll_fit_content_height
4. Put any text longer than ~10 words
5. Resize

Looks like a duplicate of #80546
