After detach tab,The zoom level of the detached tab does not synchronize until it reloads.

Because of after  detach tab,window.TabsProgressListener.onLocationChange does not fire by switching tab.

Reproducible: Always

Steps to Reproduce:
1. Start Firfox with out any add-ons.
2. Make sure browser.zoom.siteSpecific = true in about:config.
3. Click "Home Button". (1st tab)
4. Middle click "Home button". (2nd tab)
5. Zoom in (Ctrl++ Ctrl++ Ctrl++ Ctrl++).

6. Detach a tab by Drag and Drop.
7. Middle click "Home button" on the detached window.

8. Focus the original window again.
9. Zoom reset (Ctrl+0) in the original window.

10. Focus the detached window.
11. Switch the tab of the detached window.

Actual Results:  
Zoom level of the detached tab does not synchronize with the Site Specific Zoom Level.


Expected Results:  
Zoom level of the detached tab should synchronize with the Site Specific Zoom Level.
Because of "browser.zoom.siteSpecific=true (default)" and the same host as the 1st tab.

i can confirm this with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2a1pre) Gecko/20090720 Minefield/3.6a1pre ID:20090720042210 & Fx 3.5.1

remark: the issue seems to only happen using non-maximized Fx windows (like in the attached video). trying to reproduce with maximized windows fails, i.e. the zoom level in the (i'd call it 3rd-level) tab in the detached window is being resetted (or adjusted) too.

no errors in the console.

This problem can be generalized as follows .
As for the zoom level of a tab moved between browsers, it is not synchronized till page reload.
ie,It is not synchronized a zoom level of aOurTab after gBrowser.swapBrowsersAndCloseOther was carried out.
