This appears to not be the case.

158639 no longer reproduces, but this one still does sporadically.

Marked as flaky in <http://trac.webkit.org/projects/webkit/changeset/203190>

The test no longer seems to be failing according to the furthest date of 5/12 on the flakiness dashboard.
The test has however become a flaky timeout on multiple platforms see bugs:
https://bugs.webkit.org/show_bug.cgi?id=163122
https://bugs.webkit.org/show_bug.cgi?id=172403

Changing expectation files in iOS so that failure expectation is no more.

I think we can delete this test in favor of WPT:

https://wpt.fyi/results/IndexedDB?label=master&label=experimental&aligned=&q=blob-valid-after-deletion

We have both WPT imported.

Done by Blink here - https://chromium.googlesource.com/chromium/src.git/+/d52a9d0798ef5c0aa4126e2e1a60847fe2b6a128
