The 3 pane tab has multiple browser elements. Switching tabs sets the docShellIsActive property of the current browser. This can lead to a browser having the wrong value for the property and behaving slowly.
The multi-message browser is always set inactive, because it's never the current browser for this circumstance.

Note to future me: I've decided that the multi-message browser and Account Central browser don't need to be made inactive in any circumstance, as they don't contain any content which would be affected by it. The about:3pane web browser and content tab browsers only have their active state managed because tabmail sets docShellIsActive on a tab's browser member, instead of complicating everything trying to limit it to message panes.
