Plugin somehow causes File operations to just hang in browser

[notfixingit3]

OS OctoPi: 0.18.0 OctoPrint: 1.6.1 Python 3.7.3 Firefox 92.0 or Chrome 93.0.4577.63

Issue: When you create a directory or delete a directory in files, browser window just hangs and doesn't refresh even know the operation actually completed, forcing you to do a refresh in browser to see the changes.

I disabled all 3rd party plugins except GcodeEditor (although I left all bundled plugins enabled) and still have the issue. Nothing in octorprint.log helpful, however when running Firefox/Chrome Inspector you see the below failure/exception, only when GcodeEditor is enabled, octorprint loads fine without this error if it's disabled.

Reproduce: Disable all 3rd party plugins except GcodeEditor, restart octoprint, log out, when at login page, turn on Inspect > Console tab, login and watch for error below in console. Go to files and create a directory, window just hangs. Disable GcodeEditor, restart, open Inspect > Console tab or just hit trashcan icon to clear console, login, notice no error and creating directory/deleting one works as expected. I did change the IP in the below log to something random.
