Glitches with Fx 74 & 75

Just recently, an uncontained tab stopped getting reset to my default color when switching from a tab with color managed by containers-theme.

STR:
1. open new window, uses default color 'Y'
2. open new tab in container 1, uses coloy 'G'
3. open another new tab in container 2, using color 'B'
4. toggle between tab 2 & tab 3 -- color changes as expected
5. toggle between tab 1 and 2 or 3 -- tab 1 will retain color of other tab
6. decontain tab 2 or 3 -- it will retain color of prior container.
