In ZSH prompt expansion, the command %E is supposed to "Clear to end of line."

This works: enter image description here

However, it does not work in tmux: enter image description here

The issue seems to be with BCE (Background Color Erase). In screen, I can add the option defbce on. I can't find any similar setting for tmux. Does it exist?

Unlike screen, tmux does not have switchable background colour erase capability in its terminal emulator. Erasure is always with the default background colour, never the current background colour.
