Inconsistent font size in v22

Expected behavior
Font size

Actual behavior

If I go into settings, my Font Scale slider is the whole way on the smaller side (as expected).

In both cases the Font Scale slider is shown in the same position even though the font size isn't the same:

To reproduce
For me, just opening v22 demonstrates the issue.

System information
Dash Core v22 RCs on Ubuntu 22.04. I've heard the issue is present on macOS too.
