What's Wrong?

A formatted markdown bullet list typed into the prompt input box reverts to raw markdown (literal * characters, no rendered bullets or indentation) after switching to another session's tab and switching back.

What Should Happen?

The draft keeps its rendered, indented formatting when switching tabs and back.

Error Messages/Logs

None.

Steps to Reproduce

1. Type a markdown bullet list in the input box, e.g.:

• im formatted bullet list
• bla bla
• double bla

It renders as a formatted, indented list.

1. Switch to another session's tab.
2. Switch back to the original session.
3. The draft now shows raw * markdown — formatting is lost.

Reproducible every time.
