Error when trying to edit a spreadsheet cell from the upper space window

Hello,
I found a bug in Collabora spreadsheet, that I can reproduce in the online version and the Windows 26.04.1.4 version. Though its not a deal breaker, it is still a quite annoying behavior.

I made a small video to explain it better. Basically, if I want to edit text of a cell from the upper window (the white space below the header settings), it only works if my mouse is in that window when the click ends. If the mouse is outside of the window when the click ends, its like if the click was never ended, so changes are impossible.

As I said its not really a big deal once you figure out how this works, but it took me a while to know why I couldnt edit the cell from the upper window.
Am I the only one have this issue?
Thanks for your help!
