Listen for a mutation event on the sidebar element - something like
DOMAttrModified and check for changes in the "hidden" property in your
listener code.
Don't hook into toggleSidebar() unless absolutely necessary. I had to
solve conficts where two extensions both tried to grab toggleSidebar and
replace it with mutually incompatible code resulting in unpleasant side
effects.
