Mark it as flaky.

Reopen to counter auto-closing.

It should definitely never crash.

[Alexey Proskuryakov]

I don't see any crashes for this test on the flakiness dashboard. But the test fails 100% of the time:

-PASS new FontFace('family_name', 'url(\'asdf\')', {}).unicodeRange is "U+0-10FFFF"
+FAIL new FontFace('family_name', 'url(\'asdf\')', {}).unicodeRange should be U+0-10FFFF. Was U+0-10ffff.
