Just remove the lines for PP_FONTNAMESIZE and PP_USER, save the file, and you're done.
Tried commenting those lines out, rc.exe was not happy. What does seem to work is removing the font size, s/10.System Proportional/System Proportional/g.
Have to consider changing the System Proportional to WarpSans as well. There's also buttons that need the same treatment.
I'm sorry to be difficult but none of the above is the correct way to handle this.
RC should accept /* */ comments but if it doesn't for some reason, just delete them as suggested (you can always have git revert any change). Further, generating defective entries just to get something kinda-maybe working is not helping your cause. Nor is substituting one hard-coded font for another when the goal of this exercise is to have dialogs comply with the user's choice of font & size.
Without those fonts entries, the dialog will use whatever font & size you've chosen - either because it has inherited them from the dialog that created it (which is the way it should be), or because Styler has forced them to be system-compliant (turn off Styler's dialog enhancements to check).
Honestly, there's no need for any experimentation here - how this stuff works is fully known. If it doesn't work as it should, hacks and workarounds will only get in the way of finding the _real_ problem.
