Opening cmdwin from mundo window spews errors coming from MundoRefreshDelayed

[idbrii]

If you open cmdwin (default q: or :<C-f>) from inside the mundo window, you get a screen full of errors.

Minimal vimrc

" Invoke with:
" vim -Nu ~/.vim/reprovimrc.vim -U NONE

" all plugins should work with sensible as a baseline.
let s:plugins = ['sensible']
let s:plugins += ['mundo']

set runtimepath-=~/.vim
set runtimepath-=~/.vim/after
set runtimepath-=~/vimfiles
set runtimepath-=~/vimfiles/after
for plugin in s:plugins
    exec "set runtimepath^=~/.vim/bundle/". plugin
    exec "set runtimepath+=~/.vim/bundle/". plugin ."/after"
endfor
set viminfofile=NONE

" Point to your python
let $PATH = $PATH .. ';' .. expand('$USERPROFILE/scoop/apps/python39/3.9.1/')

nnoremap <F2> :<C-u>MundoToggle<CR>
nnoremap <F3> q:

Repro

1. gvim -Nu ~/.vim/reprovimrc.vim -U NONE c:\scratch\bug.txt
2. F2
3. F3

You get these errors:
