I was testing this on different OS's and on macOS the text is cut off and none
of the text renders after a certain point.
This is what it looks like when I manually move the text cursor down to scroll
the text area down a bit:

/>
I suppose this is a macOS bug. On linux (X11 and Wayland), this works fine, but
the test does not start with the textarea showing the exclamation marks.
Instead, it starts at the top. But, all of the text renders correctly when
scrolled down. When I manually append another `cool` to the text area, the auto
scroll and rendering of all the text works fine for all OS's.

/>
What I think I understand now is, there is most likely a macOS bug here and the
test fails on linux. I'll revert the changes to this test. I think this also
means I should ProblemList this test. I will, however, try fiddling with this
test to see if I can get the programmatic appending to render on macOS and
figure out the source of the issue. Maybe it will work with an added delay in
the beginning or something of the sort.
