resize font with mouse wheel changes it to SANS even in config file

[mvsite]

Version, Operative system
Current CherryTree 0.99.55 on Windows 11

Describe the bug
After I set the fonts either in the interface or in the config file, then at any point if I resize them such as with ctrl+mousewheel, then the font changes to "Sans" and this is also changed in the config file.

To Reproduce

1. Run cherrytree and have some text in the display
2. set a custom font such as Monospace
3. use the ctrl+mousewheel to zoom in changing the font size to a different size
4. at this point it will revert to Sans
