626870 - Broken Firefox Sync/Personas interaction: Switching to "Default" appearance doesn't affect browser styling on Sync peers

Status: RESOLVED DUPLICATE of bug 579843

(Firefox :: Sync, defect)

Description

[Daniel Holbert [:dholbert]]

STEPS TO REPRO:
 1. Have two machines next to each other, running mozilla-central nightly with Sync configured for their profiles.
 2. Open one Firefox window at about:addons on each machine, showing the "Appearance" subtab. (so you can see which theme is currently active)

 3. ON MACHINE A: Apply some persona, e.g. by visiting http://www.getpersonas.com/en-US/persona/16 and clicking "Wear this Persona".
 4. Use "Tools | Sync" on machine A, and then machine B.
    --> Actual results: Machine B magically changes to apply the persona.

 (Optional: Repeat steps 3-4 with a new persona. Notice it still works.)

 5. ON MACHINE A: At about:addons, activate the "Default" appearance.
 6. Use "Tools | Sync" on machine A, and then machine B.

EXPECTED RESULTS:
 Machine B should end up showing the "Default" browser appearance

ACTUAL RESULTS:
 - Machine B still shows the persona in any already-open windows. <--- BUG
 - New windows created from this point on will show "Default"
 - Moreover, about:addons ends up in a weird state -- it looks as if *both* appearances are enabled. (Both are highlighted in white, as opposed to grey, and neither has an 'Enable' button.)

(or just by clicking "enable" on some already-installed Persona)

(Actually -- If I click away to e.g. "Plugins" and then back to "Appearance", then this broken highlighting & button state becomes fixed.)

Attachment: screenshot of bug

Here's a screenshot showing the Persona still applied to the browser's chrome, but with about:addons showing that we're supposed to have the "Default" theme.

I think this is a dupe of Bug 579843.
