Bug 184362 – Layout Test imported/w3c/web-platform-tests/FileAPI/url/sandboxed-iframe.html is failing

• Component: New Bugs
• Status: NEW

[Ryan Haddad]

The following layout test is failing on macOS

imported/w3c/web-platform-tests/FileAPI/url/sandboxed-iframe.html

Probable cause:

This test is failing since it was imported in https://trac.webkit.org/changeset/230330/webkit#file143

Flakiness Dashboard:

Removed the pass expectation for mac-wk2 in https://trac.webkit.org/r230343

Not sure if this just needs a rebaseline.

[Brendan McLoughlin]

Removing the pass expectation looks like the correct fix. I don't think a rebaseline will help since the id in the blob url changes with each run.
