System information

Windows 10

Issue description

If the label get's squished into a 0 size inside a HBoxContainer control, it squishes the text into 1 column when the autowrap is set to "Word (Smart)". I've seen this also in the documentation, in godot, in various places.

Steps to reproduce

Create a new Control based scene. Add a HBoxControl. Add a Label as child of HBoxControl. Type a few words into the Label text property. Set the Label's Autowrap mode to "Arbitrary" or "Word (Smart)".
