FontPicker, FontSize and Mini Color picker: Unable to navigate using Keyboard

[yoghcl]

Hi,

I am using "PropertyFieldFontPicker" for displaying fonts in my SPFx web part. It is working fine when I use mouse to select any entry from the drop down. But when I use Keyboard, the focus is not going the drop down control.

It is not working for PropertyFieldFontSizePicker and PropertyFieldColorPickerMini as well.

Could you please check ?
