[BUG] Grouped Settings being split between Group Buttons

[LightTab2]

Description:
Adding Settings that belong to different Groups in unorderly manner like this:

add_setting(IntSetting.new("setting_2", "group 2", "my special int setting", 1, 0, 10, "pcs"))
add_setting(StringSetting.new("My string setting", "String group", "some tooltip"))
add_setting(ColorSetting.new("Color", "group 2", ""))

Causes them to display in a very unintuitive way.

Expected behavior:
The Groups should aggregate Settings, even if they are added after another Group's Settings.

Screenshots:

Notice that only Group 2 is open, so only Settings from that Group are seen.
