Hi Lofty
Since the Edge 116 update (and still happening as-of Edge 117.0.2045.43) your theme that I used to use now shows the "active-tab highlight" below all of the tabs:
I see from your Facebook post this started after a change in Chromium 116, and so it will be affecting all Chromium-based browsers (e.g. Chrome, Edge, Brave, Opera, Vivaldi).
If Google are not willing to fix this, and consider the changes to how the themes work to be "as designed, won't fix", is there any-chance you can update your themes please?
Alternatively, is it possible for us to somehow "hack" your theme by going into the folder where the extension gets installed to and editing a file? I'm willing to try if you could advise what I'd need to change?
Thanks
Stuart
