Maybe it's just me, but I think it's silly to wrap all these methods. There are
only two places where the invalidate needs to be called: once when the settings
are initialized and once for each time the InternalSettings function is called.
We should just do it then, instead of repeatedly invoking resetFontSelector at
startup.

I am not a fan of extra plumbing functions that hide what's happening :)

I see.
I reverted these changes and added "notifyGenericFontFamilyChange()" method to
update CSSFontSelector's m_genericFontFamilySettings.
