298581 - font-family property for an Element node's computed style is inconsistent

Status: RESOLVED INVALID

(Core :: DOM: CSS Object Model, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

I have noticed that the font-family property returned from an element's style
object using document.defaultView.getComputedStyle(node, '') is inconsistent in
the following two cases.

1. If a text node is enclosed using font tags like this <font
face="some_font">some_text</font>, the following code returns some_font.

var style = document.defaultView.getComputedStyle(node, '') where node is the
font element node.
var face = style.getPropertyValue("font-family"). 

The above is true even if some_font is not installed on the local machine.

2. If font is specified using CSS and @font-face, the same code for the parent
node of the text node returns serif instead of some_font. This seems  incorrect
because if some_font is available on the machine, the text is rendered correctly.

For an example of 1, please take a look at http://www.andhrajyothy.com/.
For an example of 2, please take a look at
http://www.andhrajyothy.com/editshow.asp?qry=/2005/jun/20vividha1. The JS that
is setting the font is at http://www.andhrajyothy.com/fonts/PFR_EOT.js.

It would be convinient if some_font is returned from 2 because it will help in
scripts (ex: greasemonkey lauched ones) to automatically transform the page to
Unicode.

Reproducible: Always

Steps to Reproduce:
1. I'm not sure if there are tools to inspect the DOM tree, but I wrote some
Javascript to verify this. I can post this if needed.


Actual Results:  
font-family is set different in the above two cases.

Expected Results:  
I expected them to be the same.

Can some one confirm if this is a valid bug? I can look into working on a patch
if it is a bug.

> 1. If a text node is enclosed using font tags like this <font

That's the correct behavior.

> 2. If font is specified using CSS and @font-face,

We don't support @font-face.

I can't tell whether the bug is valid because there is no testcase -- just huge pages where I don't even know where to start looking for the code you're talking about.  Please attach a testcase.

This is not a valid bug. It was a mistake in my understanding.
