[2.0.35] debug settings starts off a little too small

[Quezler]

- fresh instance
- new world
- f4
- notice "show multiplayer selection rectangles unconditionally" being slightly cut off
- use the force dropdown / collision layer dropdown / search / always-debug tab
- notice the gui widening a little bit to accomodate the longest debug setting

expected behavior: the debug settings gui does not change its width whilst it is open
