> This spec requirement doesn't appear practical. For usability and accessibility reasons, one cannot require that mouse position doesn't change at all during click, or it would be too difficult for some people to click. This is doubly important for double clicks, which are served by the same event (with the detail attribute incrementing with each repetition).

Alexey,

Yes - I think the requirement of "over the same screen location" is almost always implemented actually within a bounding box of a couple pixels. The behaviour in WebKit right now is inconsistent with other HTML elements. For example, adding the same code above to a div would produce the expected results.
