Fix MenuButton for the case where multiple listeners are defined.

This is a minimal fix suitable for merging to M38. The underlying problem is that we create a new MenuButton instance (with its own click handler) for every connection. I recently changed the behaviour of MenuButton so that it toggles the 'active' class instead of adding it so that clicking on the button while a menu is open will dismiss it. However, this breaks if there an even number of MenuButton instances for a single DOM element. The correct fix is to make the tool-bar buttons owned by the tool-bar, which is a singleton. However, this minimal fix, which restores the M37 behaviour, is a better option for merging to M38.
