Emoji picker disappears when window size is shrunk

[Juicysteak117]

Describe the bug
Odd UI bug where the emoji picker entirely disappears when the window is shrunk (ie, to half frame). This occurs after the window has shrunk to where the sidebars disappear, around ~1308px on a 1920px wide display.

There's also a tangential issue with the sidebar getting screwy for an edge case at the crossover period when the window is shrunk. See the second screenshot. Should be noted as well that there is still space for the sidebars when the sidebars choose to cut off. Might be better to have them gradually go with one sidebar going before the other.

To Reproduce

Steps to reproduce the behavior:

1. Open post editor on Web (browser agnostic)
2. Adjust window size
3. Observe

Expected behavior

The emoji picker should still be there and the sidebars should not be screwy.

Screenshots

The emoji picker is gone:

Also, as a side note, there exists an odd in-between state for a few pixels that appears to be an edge case where the sidebar gets very screwy:
