I believe IKhitron is mentioning that the URL parameters sometimes stick around after this bug.
I'm not sure. Once again: When adding the first and the second user, the autocomplete list has names of wiki centrallogin users. But when adding the third user, the autocomplete list includes nine names, that are not users. AutoID, AutoImage, and so on. Looks like the list comes from some program parameter.
