STR:
[1] Go to any site
[2] Temp allow, allow, un-trust any script
[3] Click refesh button INSIDE NS dialog box
[4] List refeshes showing new scripts encountered by Temp allow for example
[5] Expected: NS in dialog box will list new scripts encountered normally
[6] Behaviour encountered: NS creates a NEW list UNDER the original list showing changes.
This will repeat indefinitely. List will continually get longer
This ONLY happens when refreshing the page WITHIN the dialog box (clicking the green refresh button). If you click away, this behaviour does not occur.
Pictures:

After I click temp allow (for postimages.org) and refresh using the green refresh button, then the dialog shows this:

Note how it appends an entire new list - which is the one that should REPLACE the original. This will go on indefinitely. It should not be appending, but replacing
Repro anyone?
