Pure black borders/title backgrounds become transparent

[Sherirk]

• Swayfx Version:
  swayfx version 0.5 (based on sway 1.10.1)

• Debug Log:
  sway.log

• Configuration File:
  config (only thing different from default is client.focused set to pure black borders and title background)

• Stack Trace:
  Not applicable.

• Description:
  When setting the window's borders/title background to pure black (#⁠000000) they end up transparent instead.
  At first they will take the black color for less than a second and then become transparent.
  Even if you use the form #⁠RRGGBBAA the alpha component gets ignored and the borders/title background stay transparent.
  The title text itself has a pure black rectangle behind it, only the rest of the title background becomes transparent.
  When making the windows floating the border/title background stays black while moving, but goes transparent the moment you stop moving them.
  If you set the colors anything but pure black (even #⁠000001 works) then the problem goes away, at this point you can even use the #⁠RRGGBBAA form and change the alpha component without problem.

Interesting find! I'll check if this impacts upstream
