This seems randomly happen while running dom/html/test/test_fullscreen-api.html tests and cause the test timed out.
When the issue happens there the window is taller than before and there is some black area, see the attached screenshot.

This may have been resolved (or exacerbated?) by the fix for bug 1776895, which has subtly changed the fullscreen size-restoration logic.

While dom/html/test/test_fullscreen-api.html remains flaky (as seen in bug 1776996), its flakiness on Windows appears to have stopped sometime in early to mid-June — all failures since 2022-06-10 have been on Linux or Mac (or on the esr91 branch), and none of the non-Windows screenshots I've checked seem to exhibit the particular failure mode shown in the above screenshot.
For posterity's sake, the latest non-ESR windows failures occurred during testing of the following commits:

While it would be nice to resolve the mystery, the fact that this has dropped from "multiple occurrences daily" to "nothing for the past two months" probably justifies closing the bug. RESOLVED WORKSFORME.
