Font Size After Theme Change

[blaufer]

I'm probably just missing something obvious here but I've tried everything I know of. In my application, the user can change the theme by selecting it from a Combobox, and the theme changes. The unwanted behavior is that the font size also changes back to the default. I've tried resetting it after the theme change but the only way I can find to do it would be to destroy the entire instance and reload everything which is not preferable. Any suggestions?

Thank you,
Brandon

Edit: I noticed that the font size does go back to what it was set to when the theme is switched to the originally set theme. I.e. if I had it set to font size 12 and the theme as darkly when the application was first started, then the font size will go to the default when the theme is changed to anything else but will go to 12 when darkly is selected again.
