Comment:

 @anevins can you provide some more steps to recreate this? The error noted
 on the support ticket is

 `Uncaught TypeError: Failed to execute ‘insertBefore’ on ‘Node’: parameter
 1 is not of type ‘Node’. at prependElement (priority-menu.js:47)`

 I am only able to trigger the following similar but different error when
 the screen size is less than about 100 pixels wide: `TypeError: Argument 1
 of Node.insertBefore is not an object.`
