Attachment: Bug 1589470 - Wait for the temporary favicon to change before validating. r=jdescottes!

Comment 9

[Logan Smyth [:loganfsmyth]]

I don't think my patch broke anything, but it may have increased the likelihood of this being flaky by either

• causing the target to pause for a second to load the content process target
• making about:debugging query the favicon earlier than it did before
