transparent_background should not make NormalFloat transparent

[PaperbagWriter]

Is your feature request related to a problem? Please describe.

I've recently upgraded to the latest version. Had to mess a lot with transparency, which was working as expected before.

With the upgrade, setting the transparent_background = true (an option I did not have before) every backgrounds are now transparent. Making it very hard to see elements such as floats and any other UI element which do not have borders.

Almost all NormalFloat elements do not seem to have borders so I believe this should be the default behavior.

Describe the solution you'd like transparent_background should not override NormalFloat elements transparency. These element background should respect regular theme.

Describe alternatives you've considered

I was able to mitigate the problem by doing:

      custom_highlights = function(colors)
        return {
          NormalFloat = { bg = colors.base, fg = colors.text },
        }
      end,

I've been trying to figure out how to do this. And was about to make a request.

+1 to this

I've been trying to find a way to mitigate this for a while

Would definitely be nice if it was a built-in option
