288945 - clicking links in client-side image maps scrolls the page to the bottom of the imagemap, making it impossible to click some imagemap links

Status: VERIFIED FIXED

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

Description

[Jan Darmochwal]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050402
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050402

A large image with an image map is inside <a>-tags like this:
   <a href="blah"><img src="image" usemap="map"></a>
(This is probably not good style, but I haven't found anything in the html specs
forbidding it and validator.w3c.org does not complain.)

If you click one of the image map's links, there are two possible cases:
  1) the bottom of the image is on your screen:
    The browser will follow the link.
  2) the bottom of the image is not on your screen:
    The browser will jump to the bottom of the image.

This makes it impossible to follow links at the top of large images.

The jumping behaviour also occurs if there is an image (with no image map)
inside <a>-tags, but the browser will follow the link anyway.


Reproducible: Always

Steps to Reproduce:
1. click the "button" in the testcase

Actual Results:  
Mozilla jumps to the bottom of the image.


Expected Results:  
Mozilla follows the button's link.


This bug is related to bug 105894 (fixing bug 105894 would probably fix this one
as well), but it does not depend on it.

This is a Seamonkey only problem, works for me with Firefox 1.0.2.

Attachment: Testcase without link around image

This is almost the same testcase as attachment 179563 [details] except that there is no
extra double quote character and the image is not embedded within a link.
