Draw borders around entire containers

[JimmJam]

The current behavior of Sway and SwayFX does not allow for drawing a single coherent border around an entire "tabbed" container, leaving unfocused tabs with an awkward, out of place feel unless you draw a border around the titlebar itself on all four sides. It would be very neat if you were able to draw the currently focused window's border around the entire container.

I'd like to see this feature too!

This would be a huge improvement, borders on tabbed containers look terrible currently.
