This page navigates to a 2nd page using the API that sets the "should open external URLs" flag to true.<br>
That page then programatically redirects to a 3rd page.<br>
That navigation from the 2nd page to the 3rd page should still have the flag set, because the flag propagates through main frame loads.<br>
