What's Wrong?

When claude asks for permissions, it stops displaying the color set by /color

This means if I have multiple terminals open on different virtual desktops, when I swipe back to find that terminal session the visual cue of the color is gone.

What Should Happen?

Ideally the color should still be displayed somewhere when claude is asking for permissions. I use tui mode so a colored bar across the top of the screen would be really helpful.
