Locale styling changed after the last wingpanel update to white color over white background

[nnmlss]

Describe the bug

After the last update of the wingpanel the styling of locale indicator was changed - white text over a white backgroud, or black text over a black background depending of the color of the wallpaper.

Expected behavior

I don't think that this is a conscious decision made by the design team that's why I post it here - it is difficult to read the text of the locale only by the drop shadow effect.
I expect different colors of the text and background, even better will be if there is no background, only the text colored with the wingpanel style
