Gleamio Twitter Unfollow not showing

[nihaals]

I have had issues with this userscript for a while now and this is one example, however, there are many issues with buttons not showing to revert things, if you find a fix for this specific bug it might help with the others. Some errors in console after loading a Gleamio page and following on Twitter:

SecurityError: Permission denied to access property "document" on cross-origin object Seems like it could be the issue.
