Bug 258865 – Attachment ref-tests should wait for the icon to be present

• Component: HTML Editing
• Status: RESOLVED FIXED

[Gerald Squelart]

Attachment ref-tests don't add any delay before a snapshot is taken. However, attachments request their icon asynchronously during their first paint, meaning that if the snapshot is taken after this first paint it will probably not have the icon!
So I'm suspecting that ref-tests don't actually compare icons, and that intermittent failures could be due to the odd case when the icon is available unexpectedly fast.
To fix this, tests should delay the snapshot until all attachments have received their icon.

REGRESSION (265615@main): [ iOS macOS wk2 ] Four fast/attachment/cocoa/wide-attachment tests are flaky image failures

After landing 265615@main, some wide-attachment-* tests became flaky because of the way the icon is asynchronously fetched and then loaded into an img.

Description:
fast/attachment/cocoa/wide-attachment-folder-icon.html
fast/attachment/cocoa/wide-attachment-icon-from-file-extension.html
fast/attachment/mac/wide-attachment-title-with-rtl.html
fast/attachment/mac/wide-attachment-type-attribute.html

History:
https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&test=fast%2Fattachment%2Fcocoa%2Fwide-attachment-folder-icon.html&test=fast%2Fattachment%2Fcocoa%2Fwide-attachment-icon-from-file-extension.html&test=fast%2Fattachment%2Fmac%2Fwide-attachment-title-with-rtl.html&test=fast%2Fattachment%2Fmac%2Fwide-attachment-type-attribute.html&platform=mac

Since the resolution is being worked on in this bug, I have marked these tests as flaky image failures here while this issue is investigated.
