How can i change the background color of selection text when it's in TextBox or EditableText?

Apparently this is a problem nobody is running into? I mean this discussion was the only proper hit the forum search brought up while google also found this: DISCUSSION

Anyways, apparently there are 4 textbox widgets:
TextBox
Multiline TextBox
Editable Text
Multiline Editable Text

TextBox doesn’t even allow changing selection color or caret, while MultiLite TB has way more problems.
Editable Text has a different selection color and allows caret styling but you still cannot change that selection color.
Multiline ET on the other hand has no caret styling but allows changing the selection color.

Like… I don’t even know why. Are textboxes not used at all?
