One of Russian user of Geany reported about strange behavior in this plugin
after 1.24 release.

Plugins enabled: numbered bookmarks, zencoding, treebrowser, addons, geanyvc,
pairtaghighlighter, splitwindow, htmlchars.

* while moving through document old tags are still highlighted with unexpected
  behaviour
* while switching paired tag/single tag, highlight color is changed for all tags
  simultaneously

* looks like highlighting remains after leaving closing tag

Bug reproducible while moving cursor up/down or while random mouse clicks.
