Very narrow fixed widget width when zooming in or out

Hi there, Advanced Ads Team!

I have an issue with the plugin. When a widget is fixed (this is the widget at the bottom of the sidebar), if I do zoom in or zoom out (with Ctrl + or Ctrl -), the fixed widget becomes very narrow and tall. The rest of the widgets adjust themselves in a responsive manner, but the fixed widget becomes ugly and unusable.

If I try to go back to the original zoom level, the fixed widget does not correct its width. Only when I reload the page, the widget restores its normal width.

I have only text links in the fixed widget.

I hope this can be somehow fixed.

Thanks and regards,

Todor
