Tests should only be checked in later, after an official Firefox release that contains the fix has been live for at least four weeks

The fix is in Firefox 114, https://bugzilla.mozilla.org/show_bug.cgi?id=1828130#c12
Firefox 114 is released on Jun. 6, so this test should be checked in 4 weeks after Jun. 6, which should be Jul. 6.
