When clicking around fast ui locks up

Steps to reproduce: build in release mode and switch chats fast (clicking around fast for some time)

What happens: it locks up with a spinning/waiting cursor

where does this happen: https://github.com/dignifiedquire/dreamer/pull/17 (it seemed to also happen on main branch)

Reproduce the lockup by building in release mode and switching chats rapidly, then inspect the logged dreamer::widgets::mainpanel rendering and eframe::native::run repaint activity. Compare the release and debug traces, including async_imap::imap_stream, and consider the issue done when rapid chat switching no longer leaves the UI with a spinning or waiting cursor.
