139495 - Display ALT in IMG tag as tooltip

Status: VERIFIED DUPLICATE of bug 25537

(SeaMonkey :: General, enhancement)

Description

[msgport]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0rc1) Gecko/20020421
BuildID:    2002042108

Suggestion to display the ALT text for IMG as tooltip. There is also a minor
problem that I don't know whether it is a feature or a bug. Say some tooltip
text that has two lines or more, mozilla will display them in one line and
truncate if it is too long.

To Reproduce:
<a href="any.html" title="Line 1
Line 2">Link</a>

IE will display it as a multi-line tooltip while mozilla will display it as one
line only.

The ALT-tag-as-tooltip part is bug 25537, marking DUPLICATE.

Regarding multiline tooltips: the title attribute is of type CDATA. 
The HTML4 standard says about CDATA
<http://www.w3.org/TR/REC-html40/types.html#type-cdata>:
"User agents should interpret attribute values as follows:
 [...]
 * Ignore line feeds"

Hence, this part of the bug is INVALID.


Reporter, for future reference: only report one bug per report.
