Fails to reopen all tabs after accidental "close other tabs"
I accidentally clicked "Close Other Tabs" in the notebook context menu and lost all my tabs. After panicking (my tabs are my TODO list), I started using Ctrl+Shift+T to reopen all the closed tabs one-by-one.
Sadly, it only reopened about 10 seemingly-random tabs or so. The other tabs were lost. Requires further investigation to determine what's wrong here.
