The anchorEl prop provided to the component is invalid.

Hi, I think you have a bug that when you resize the window to a limit, the menu button shows up, when you click the icon and the menu opens and then resize back to full screen the menu doesn't close it just taken out of the dom and then when you resize the window again it shows the menu. during this manauver this warning is fired "The anchorEl prop provided to the component is invalid." I think the menu should be closed if you have enough width to show the navlink in the toolbar!
