I had a discussion with Anna from the accessibility team about this bug.
The alt-text that briefly shows up prior to image load is expected browser behaviour on Firefox.
If we try to remove the text before image load or if we change the alt-text color to be transparent, it would no longer be deemed inaccessible. Alt-text displays if an image loads slower on slow connections/fails to load/if images are blocked by default, so it's a good fallback to have in almost any case.
I'm confident enough to say that this bug doesn't need to be fixed + shouldn't be a blocker for launching the IAB Banners to release.
I'm going to go ahead and close this bug as a WONTFIX. Thanks for filing it, though!
