Forum:Categories disappearing when login on edit screen

I was wondering if anyone could help by seeing if this bug affects them. It seems odd that it would only affect me, but I sent a report to special:contact with very clear instructions and apparently they can't reproduce it.
 * 1) Set your preferences to edit in source, and disable the category module. Ie, the editing window is completely in source, and at the bottom the categories appear like  or whatever.
 * 2) Log out of your account
 * 3) Click edit on any categorised page. As you're logged out, the category module should show the categories, and they should not appear at the bottom of the source code.
 * 4) Then log in, while on the editing screen.
 * 5) Now at the bottom, the categories do not appear, even though you're logged in with your preference to not use the category module
 * 6) Hit publish without editing anything, and hey presto, all the categories are removed from the page.

Am I honestly the only one experiencing this when I log in on the editing page?-- Category:Acer4666 22:53, January 19, 2012 (UTC)


 * I believe this was reported before. Best to and C/O: Kirkburn on it. Rappy 23:02, January 19, 2012 (UTC)


 * Awesome, cheers - the bug ticket must have got lost, as I've had a back and forth with DaNASCAT trying to explain the problem, finishing with him saying he can't reproduce it-- Category:Acer4666 23:03, January 19, 2012 (UTC)
 * Just to check - you can reproduce this, can you?-- Category:Acer4666 23:21, January 19, 2012 (UTC)


 * I can attest that this happens to me. (at least, it did last month, last time it happened) ForestMonthZero 07:26, January 20, 2012 (UTC)
