If a heading like Class, Members, Methods, or Properties is selected, the current behavior is that it both collapses/expands that portion of the tree and also adds a step in the browser's history. I find this frustrating when browsing the API because all links to such classes/methods/etc. navigate to the collapsed version. It even adds a history step if one right-clicks on the tree item. Expanding/collapsing the tree should not be registered in the browser as a history step.
