55995 - Image map areas defined with 'A' element don't work

Status: VERIFIED INVALID

(Core :: Layout, defect, P3)

Description

[Niko Pavlicek]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; m18) Gecko/20001010
BuildID:    MTrunk 2000011004

Look at "embedding objects", this object should also act as an image map, but it
doesn't in Mozilla

Reproducible: Always
Steps to Reproduce:
go to the above URL and try to find links on the object.

Actual Results:  you can see the image, but it doesn't act as an image map

Expected Results:  it should act as an image map :-)

Perhaps it is an error in the code, but the W3C HTML Validator claims it is
correct HTML 4.0 Transitional

OK, we had a conference and it's a bug.  Mac 10-09-10.  Took longer than expected 
thanks to tever.  CC:ing him also just for kicks.

Giving 5 of clayton's bugs to joki for triaging.

The problem is not with OBJECT, but with A element.  OBJECT image maps work 
perfectly when you're using AREA instead of A to define the areas.  Updating 
summary and adding 'html4' keyword.

(I think it's a dup, but I couldn't find the other bug right now.)

Some additional test cases for image map OBJECTs to prove my point:

Suggested release note:
"HTML 4.0 allows link areas in image maps to be defined with the A element as 
well as the AREA element.  This is not supported in this release.  Workaround: 
use the AREA element instead."

Okay, well at least I understand what its doing if not why.  <a> tags do work 
but only when enclosed in a block element like a paragraph.  The code is set up 
to do that, though I couldn't tell you why.  If I can't find a reason for it 
I'll just get rid of it and allow them as directly children of the map.

Cool.  Okay well a little more research has shown the cause.  The map in 
question is in fact invalid.  The <map> tag must contain a block element and 
cannot directly contain anchors.  If correctly contained within a block element 
this seems to work.  Closing.

It seems you're right - my three test cases at
http://www.student.oulu.fi/%7esairwas/object-test/imagemaps/ are in fact buggy.

The original test case of this report (http://www.icab.de/test.html) is valid,
though, and it works perfectly in my Moz 0.8.1 (Linux).  So this bug would be
either Worksforme or Invalid, depending on your point of view.

Verifying Invalid.

SPAM. HTML Element component deprecated, changing component to Layout. See bug
