Status: RESOLVED WONTFIX

window.messageManager.loadFrameScript() can be used to load content scripts into all existing tabs in the window. However, this method doesn't work as I expected when there is any tab which is moved from/to another window.

Steps to reproduce:
1. Open two browser windows, A and B.
2. Open two tabs in each windows. Then, the window A has two tabs A-1 and A-2.
   The window B also has two tabs B-1 and B-2.
3. Move the tab A-2 to the window B. Then, the window A has only one tab A-1
   and the window B has three tabs: B-1, B-2 and A-2.
4. Run following script in the window A.
----------------------------------------------
var script = 'data:application/javascript,'+encodeURIComponent(<![CDATA[
      content.document.title = 'LOADED';
    ]]>.toString());
messageManager.loadFrameScript(script, false);
----------------------------------------------
5. Reload all tabs: A-1, A-2, B-1 and B-2.

Expected result:
The only one tab A-1 in the window A has the tab label "LOADED".

Actual result:
Two tabs, A-1 in the window A and A-2 in the window B have the tab label "LOADED".


If you do the step 4 on the window B, then, all three tabs in the window B should have the label "LOADED", but actually only two tabs B-1 and B-2 (they are originally generated in the window B) have the label "LOADED". The script is not loaded to the tab A-2 even if it is in the window B.

Oops, the step 5 is unnecessary. Please ignore the step 5.
