After revoking authorization of one user from a tool (table saw in this case) from the dashboard of that tool, if I want to revoke a second user I have to refresh the page.
After revoking the first user, I get a confirmation dialog. Once I confirm, a green checkmark appears in the same dialog box which self-dismisses.
If I try to then revoke a second user, I'm not prompted to confirm, it skips right to the green checkbox (which doesn't self-dismiss). Refreshing the page shows that revoking the second user was not processed.
