Description Vincent Bernardi 2011-08-30 07:14:36 PDT
Created attachment 105622 [details]
HTML source of the page which doesn't add/remove a style element.

<http://test.elvanor.net/js/webkit/element_from_point_works.html> (A)
<http://test.elvanor.net/js/webkit/element_from_point.html> (B)

In the above pages, I have a div and a hidden span inside. There's an inline script on both pages which logs what element was clicked using document.elementFromPoint. The script on the second page  (B) also creates a style element, adds it to <head> and removes it instantly. 


I believe the expected logged element (on both pages) when clicking the div is <div>, since the span is hidden.
Expected:
(A): Div
(B): Div

Here's what is logged when clicking on each page:

Chromium 13.0.782.215 (Linux) :
(A): Div
(B): Span

Safari  5.1 (7534.48.3) (Mac OS X 10.7) :
(A): Div
(B): Span

Safari nightly 5.1 (7534.48.3, r94061) (Mac OS X 10.7) :
(A): Span
(B): Span

Google Chrome 13.0.782.215 (Mac):
(A): Div
(B): Span
