176621 - MouseOut fired when entering input[type="text"]

Status: NEW

(Core :: DOM: Events, defect, P5)

Description

[Dan Allen]

This could possibly be more instances of form elements, but if you put an
onmouseout on a form element of type="text" and head slowly into the element,
you will find that after crossing the border (which is where the mouseover is
correctly fired) you will see the onmouseout fire just as you drop into the
actual text entry section (if you leave the cursor at the default setting you
will see it change at this point).  This is obviously not correct as a border
and element must be considered one in the same.

events.  Seeing this with an Oct 22 build as well.  I checked and the event
target is indeed the <input>

Probably has something to do with the way textboxes work internally, ccing jkeiser

This would be because the textbox has an anonymous <div> in it, so when the
mouse moves from the textbox to the anonymous div, mouseout is fired on the
textbox.  A very difficult problem; on the one hand, content shouldn't be told
that things like this happen on a <div>, but on the other hand, the <div> itself
might need to know.
