Bug 1966586 - Reuse other browser windows when opening _blank links in Taskbar Tabs windows. r=nrishel This doesn't affect other tab additions, nor does it stop the tab bar from appearing altogether. The idea is that _if_ another tab is somehow made, the user should see it; but we should not create new tabs if we can avoid it. This also adds tests for opening URIs in popups and taskbar tabs to make it less likely that this breaks in future. Differential Revision: https://phabricator.services.mozilla.com/D253726
