16548 - [EVENTTARG] events going to wrong element: inline elements and overlap

Status: VERIFIED FIXED

(Core :: DOM: UI Events & Focus Handling, defect, P3)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

See also the following bugs relating to events going to the wrong elements:
bug 1413, bug 12231, bug 12232.  In particular, this bug will act differently
when bug 12231 is fixed.

DESCRIPTION:  Since inline elements are all above block level elements (this is
because of the rules for z-order around floats), the events should go to inline
elements, since they're on top.

STEPS TO REPRODUCE:
 * load attached test case
 * hover over / use the links

ACTUAL RESULTS:
 * the link on the bottom doesn't work in its first line or part of its second
 (note that when bug 12231 is fixed, the problem will occur with the link on the
top instead)

EXPECTED RESULTS:
 * the links work, since a block level element should only recieve events if
there are no inline elements at that position (assuming everything is in the
normal flow,... it's more complicated with positioning).

DOES NOT WORK CORRECTLY ON:
 * Linux, viewer, 1999-10-15-11-M11

WORKS CORRECTLY ON:
 * most other browsers, I think

ADDITIONAL INFORMATION:

causes problems.
