Missing/transparent color on Tilix title

[curtisbelt]

Hello! First off, great theme thank you :).

So on my terminal (Tilix), there is this bar that is transparent on your theme, but not others. I am not sure how tell you "which color setting" that is as far as your theme's code goes. Please let me know if there's anything else I can provide.

Here it is with Adwaita. Also tried Arc, Qogir which I have previously used. All of them have this bar colored.

Yes there have been many such issues after I performed code cleanup. Will refactor the code base again in the next release.
