The test error zone is not very useful

[aeschli]

Testing #21861

When selecting a failed test item, the editor gets focus and the test failure is shown in an editor zone

• the error points to the definition of the test. It would be more useful if it points to the assertion that failed. Also note that the arrow of the overlay is pointing to whitespace
• the editor overlay is very large. Is seems to cover the rest of the editor. The larger the editor the larger the zone. It would be nice if it's only as big as the information it shows
• the editor zone repeats the information already shown in the title. test_subtests.NumbersTest.test_even (i=7305) is shown 3 times in the zone, plus as ghost text in the editor
• the stacktrace is not useful. It doesn't have links to navigate to the locations. But I doubt I would want to navigate to the locations as they point in to the python unittest test runner

The second bullet is something @connor4312 and I had been discussing. The rest I will look into! Thanks

The widget defaults to approximately the number of lines in the error message, unless the widget was previously resized by the user in this session. In that case, the user's size is taken. I'm guessing the latter case is kicking in here.

I can't reproduce the issue on my home machine. What I see here is what you describe in #22312 (comment). One I manually change the height it sticks to that height.
