This looks pretty permafail on QR debug runs. Do we just need to update the test expectations here?

The frequency in the last few robot comments doesn't seem very high. But if it is permafail, sure, update the expectations.

Priority: -- → P3

Just for the record, as of today, this test is still failing, in that the test image generally renders wrong (the dividers between the tabs are too long and overlap the border around the tabstrip). But there are a few intermittent passes where it seems to render fine. The failure rate seem low enough that we should just leave it as fails-if rather than changing it to random-if or skip-if.
