Description of the bug

When opening the flyout and selecting the category, the flyout out crash and close.
Is your bug already reported? [y/n]: n

When opening, the flyout and selecting a category with a lot of options, the flyout would crash and close. This does not happen on my other machines running the exact same OS. This issue may be caused by the low resolution of the display (1366 by 768); it could be that the flyout does not fit.

To Reproduce

Steps to reproduce the bug:

1. ...Open the flyout from the bar
2. ...Select the second category
3. ...

Expected behavior

The flyout should remain open and allow me to select an emoji.
