When I tried to show unanswered JavaScript questions not related to jQuery on SO, it showed on the right that it was showing questions tagged with "javascript not jquery" (example). However, both the number of questions and the actual questions shown do not correspond to the description given by the page. Is this just me, or is this actually a bug?
EDIT: doesn't just affect Stack Overflow (example with Programmers.SE):
EDIT 2: This does not affect the "or" operator - [javascript] or [jquery]
works fine.
