[whatwg] JavaScript Hovers and Back Button

[Michael A. Peters]

It needs to be made very clear as a web standard that no JavaScript 
action can disable UI functions such as the back button.

A very common abuse is that when pulling the mouse to hit the back 
button because you are not interested in a page, a hover comes up and 
when the hover comes up, the back button no longer works.

This is a browser UI issue but it needs to specified that browsers must 
not disable the back button in response to JavaScript. The web is enough 
of a cesspool as it is.
