The change in bug 1833814 started permacrashing some TB tests, which apparently reproducibly destroy presshells/prescontexts that have open popups.

There were also some intermittent failures on m-c, but they weren't frequent enough to get the regressing change backed out.

This seems like an edgecase we could reproducibly trigger in automation that is likely to catch future mistakes in this area, so it seems worth adding an automated test.
