* Bug 1100223. Calling browser.loadURI() while a tab is loading causes
* sessionstore to override the desired target URL. This test ensures that
* calling loadURI() on a pending tab causes the tab to no longer be marked
* as pending and correctly finish the instructed load while keeping the
* restored history around.
