Found this separate bug in the course of investigating Chinese lookup not working - #4 by agilgur5
When I am reading something in Chinese (e.g. MA1 with Chinese line-by-line or DA1’s root text) and click the button to switch to simplified, it breaks dictionary word lookups.
Even if I switch back, they are still broken. Even if I disable word lookups and re-enable them, they still won’t work. I have to refresh to get it back.
