Attachment: Bug 1794937 - Remove mr2022 test leaving open tabs

Comment 19

[Emily McMinn :emcminn]

The intermittent in question seems to be caused by Firefox View tabs being opened in the background of the experiment windows opened by test_mr2022_templateMR() & not having time to close fully some small percentage of the time. (Particularly on Linux.)

Since we're no longer using majorRelease2022.onboarding and this test exists only to check the interaction between majorRelease2022.onboarding and aboutwelcome.templateMR, we should be fine to remove it, and it does seem to solve the intermittent.
