Created attachment 67693 [details] video showing bad behaviour. To reproduce: In A1, enter "abc" In A2, enter "=if(A1="";"";A1) ->A2 now contains "abc". Good Select A1 and Delete (backspace/del) ->A2 still contains "abc". Not good. Expected: blank cell. Homebrew clean master build: Version 3.7.0.0.alpha0+ (Build ID: 01e6335) attaching an ogv. Haven't tried other formulæ yet.
looks like https://bugs.freedesktop.org/show_bug.cgi?id=55059, but this is an issue in 3.7 still.
Autocalculate is on F9 does nothing Ctrl+Shift+F9 calculates well.
I can't confirm this with build: Version 4.1.0.0.alpha0+ (Build ID: dfd474710f959dcf78038deb990c3618b467ec6) Please test with newer pull and if it's still a problem for you reopen as UNCONFIRMED. Marking as WORKSFORME.
