wrong pagination/topic count in forum when filtering by tags

[deschle]

• go to ​http://testbp.org/forums
• click on a forum topic tag on the tag cloud on the sidebar

-> the pagination numbers on the top of the page do not match with the actual topic count

e.g. clicking on "topic" tag shows 7 topics but it says "Viewing topic 1 to 20 (of 90 total topics matching tag "topic")". Also pagination links don't work as expected.

Confirmed.

I spent a bunch of time with forum pagination and AJAX late in the 1.5 dev cycle (see #3557). My guess is that this problem is limited to forum topic tags, which I don't remember looking at explicitly. If so, it's somewhat lower priority than if there were a more general pagination issue.

(In [5433]) Do a proper topic count when viewing a forum tag archive. Fixes #3761
