active-trail class not getting added to menu list element when using views

Consider the primary-menu block added to one of the page regions.
When a menu item is selected the 'li' element normally gets the 'active-trail' class added and the 'a' element within get the 'active' class.
However if a menu item has been added that maps to a 'Views' module path, the 'active-trail' class does not get applied to the active menu element.

There is at least one similar bug-report. ...

I cant figure out from the reports if it was fixed or not and what version of D6 fixes were applied to. Or maybe this is not quite the same issue.

Anyway, I can confirm there is still a bug in D6.26 and D6.x-dev.
