MDTextField setting font_name does not take effect, how to solve it?

Description of the Bug

Judging from my own testing, the font_name setting of the MDTextField sub-control MDTextFieldHintText is effective and can indeed display Chinese, but the font_name setting of the MDTextField itself does not seem to be effective?

In my sample code: print(text_field.font_name), get the result: Roboto print(text_field.children[0].font_name), get the result: ChineseFont

How can I make the custom font_name set by MDTextField take effect?
