Description hsnnsnc 2020-02-11 20:42:47 UTC 
SUMMARY
The process of opening the emoji selector (Meta +.) And the process of resizing the window and being full screen is very slow.

STEPS TO REPRODUCE
1. Meta +. with the combination of "Application menu", "Utilities", "Emoji Selector" Is the app's name "Emoji Picker" or "Emoji Selector"?
2. The opened window is made full screen, it becomes normal again.
3. The opened window is resized. It appears that the window does not have the smallest size.
4. Click on "Close Sidebar"

OBSERVED RESULT
In general, "Emoji Picker" reacts extremely slowly. It's not useful.

EXPECTED RESULT
Better response times and fixing the smallest size of the window.

I've tried to fix the layout slowness, and add some lazy loading for the emojis.
