Toolbar can't reflect the font type of RichTextLabel #10
Description
The font type is always shown as "None" when open a scene that consist RichTextLabel with fonts that previously set by UIDesignTool's toolbar.
This is a known limitation of UIDesignTool's toolbar, as it is dedicated to edit Control with single font.
So, it doesn't make much sense to reflect RichTextLabel's font type out of the five font weights (normal, bold, italics, bold italics & mono), as they are not necessary from the same font type.
What the toolbar does now, is simply override all fonts of RichTextLabel when setting font from toolbar.
