Attempting to set new access control on resource results in "Error: Drop fails to drop appropriate thing!"

[AJamesPhillips]

Bug

I see the error: Error: Error: Drop fails to drop appropriate thing! https://solid.github.io/solid-ui/src/icons/noun_98053.svg when I try to change the access control for a resource by adding "Add Everyone" to "Viewers.

Steps to recreate

1. I created a directory in my root solidcommunity.net pod called getting-started
2. I visited https://.solidcommunity.net/getting-started/
3. I clicked on the padlock and then on the first green plus icon
4. I drag and dropped the "Add Everyone" icon to the "Viewers" row.
5. The error was shown.

Additional context

Once, somehow, I managed to "Add Everyone" to the Viewers list but I was not able to recreate that.

I can't reproduce your problem. Can you give more context : OS, browser, mouse/touchscreen

OS: MacOS 11.1 Chrome & Brave Mouse and built in touchpad

Looks like it might be a CORS error?

I was able to recreate the error when moving the Eveybody icon. The same error arise with Authenticated Agent There is no error when you click on the icon and do not move it.

Thank you. Yes I can confirm that if I click on the Everybody icon it places it into "Viewers" from which I can drag it to other permission levels. Thank you. I will leave this issue open as you have added the Bug label.
