Nav with duplicate words "breaks"

[Miro-Collas]

I have this snippet to make a nav bar:

<nav type="tabs">
  * [[preferences_general_tab|General]]
  * [[preferences_chat_tab|Chat]]
  * [[preferences_colors_tab|Colors]]
  * [[preferences_custom_colors_tab|Custom Colors]]
.... etc
</nav>

Having the word "colors" repeated in "Custom Colors" results in the nav button not being highlighted when I navigate to the "Custom Colors" page. Most subsequent pages also do not highlight correctly. If I change "Custom Colors" to "Custom", then it all works as expected.

(Added:) Oddly, this works fine:

<nav type="tabs">
  * [[problem_how_to|How To Document Problem People]]
  * [[problem_people|Problem People]]
.... etc
</nav>
