I get minor problems with the display of the flags added through the plugin polylang. I’m not sure you can fix it on your side, but I’m still asking here first as you are much more reactive than polylang..
So here is my problem:
When I hover the flag to change language, I notice that the flag is not centered compared to the underline (or vice versa), seems like it’s align left, while other items on the menu are centered.
Then when I put the mouse pointer a bit on the left side of the flag, the attribute ‘title’ of the flag img file appears, and it’s very long and ugly. This seems to be more of a polylang issue but if you can see a way around it to fix it that would be great.
