Using emacs-server and emacsclients, I used my window-manager to get to
another emacsclient window and write these mails with gnus. But to
continue working on my markdown-clone.el and the test.md file, I had to
restart emacs-server.

I now fixed all those errors for my usecase. If its worth to fix the
general behaviour would be your decision, thats a bit too specific for
me to be of any help there. Only wanted to report the problem.
