contextmenu click on second element shows and immediately hides the menu #585
Description
I'm using the menu in conjunction with vis.js Timelines and it's causing an interesting edge case. Here's a demo to see the issue in action. The demo is divided into a simple list at the top of the page, and a series of vis.js Timelines at the bottom.
Both lists are using the selector option to delegate handler functions.
If you right-click from one item to another in the top list it works just fine, however, if you right-click from one Timeline to another you will eventually cause a case in which the menu will open and then immediately close again. This will also break the top menu.
I looked briefly at the code and it looks like the menu is designed to close its previous instances when a new contextmenu event is fired, however, in this case it's closing the menu that was just opened.
If you have any suggestions for a workaround or a fix I would appreciate it.
