Expand/Collapse behavior in docs navigation gets reversed

[kcoleman-marklogic]

From @popzip, via internal bug report:

Click into this section of the docs. Switch back and forth between JS/XQ version of the function (by clicking top right). Somehow the behavior of the top two items in the navigation gets reversed where (+) means it is expanded already (vs click to expand). Hard to reproduce but if I click enough it happens. Screenshot attached of the mismatched behavior. Not sure if this is a rundmc bug or belongs here.
