shellshare doesn't share anything and won't exit

[larsks]

I'm trying to run shellshare on Fedora 33 (python 3.9.1). It runs without errors, prints a URL, and starts a new shell session, but when opened in the browser there is nothing but a blank screen with a blinking cursor in the upper left. Activity in the local shell never shows up in the browser.

When I attempt to exit the shellshare-spawned shell, it hangs. Hitting CTRL-C produces the following traceback:
