Steps to reproduce the issue
Open the Options in eg articles manager or global settings
Compare width of switcher with list (dropdown) or text fields.

Expected result
Reasonable sized dropdown and text fields.
Ideally, all fields are about the same width (like in J3).
Actual result
All text and list fields are spanning over the whole available width while the switcher type is hugging the left side.
Resulting in unneeded clutter and mouse move
