Looks like it's failing on this line:

kibana/x-pack/test/functional/apps/spaces/spaces_selection.ts

Line 112 in c321910

await PageObjects.spaceSelector.expectSearchBoxInSpacesSelector();

Probably the same root cause as #99581, which we still haven't figured out 😫
It seems like either the Spaces nav opens and then immediately closes, or it never opens at all.

This test keeps failing and looks flaky. Skipping for now.
