Briefly describe (1-2 sentences) the Bug you’re experiencing:
After I have clicked on a task so it opens a window, if I click on the due-date of a sub-task it opens a pop-up (calendar, times) which often puts the time and repeat choices off the bottom of my screen, unreachable. workaround - click on subtask in task-list directly, and pop-up is higher on the screen and reachable.
This is a minor bug, but might be an enhancement sometime to check cursor location on smaller device screens and pop-up upwards not downwards as appropriate.
Steps to reproduce:
( see description above)
Browser version: FireFox 71
