yeah, that's a new test introduced in Bug 1602384.
The patch didn't actually regressed an existing test, but these failures show that the new test case can currently fail intermittently because of BrowserTestUtils.synthesizeMouse throwing.
There is a call to await window.promiseDocumentFlushed(() => {}); in the test case that was meant to prevent it (I added it when I saw the error triggered locally once), but it seems to not be enough and it was likely just making it a bit less frequent (because of the little additional latency it does introduce, but not enough to fix the intermittency on an higher number of runs :-( )
I just checked that I can also trigger this failure locally by using --verify and I'm looking into it.
