System information

Issue description

Creating a theme, which is set as the default theme inside the project settings, lets me change the font color of a button, but the setting for the font type is just ignored, even though the different font is visible in the preview.

Steps to reproduce

1. Create theme, set button font
2. Set theme as default in project settings
3. Add a button to the scene
