Setting GtkFontChooserDialog:font does not work
Using gtk_file_chooser_set_font()
or gtk_file_chooser_set_font_desc()
does not select or scroll to the provided font. This is problematic for situations where the user expects to just open the dialog, tweak the size, and close, as they might get another font.
It looks as if it might set it very initially, and then after the list loads it immediately switches to the first item in the list, overriding the programmatically set value.
Seeing this in gnome-text-editor's font chooser preferences.
