Bug 12874 – execCommand FontSize -webkit-xxx-large instead of passed px value

• Status: RESOLVED
• Resolution: WONTFIX
• Component: HTML Editing

[Peer Bremer]

document.execCommand("FontSize", false, str);

Before passing "10px" to this function produced:

<SPAN class="Apple-style-span" style="font-size: 10px;">Text</SPAN>

Now this gives me no matter what I pass:
<span class="Apple-style-span" style="font-size: -webkit-xxx-large;">Text</span>

compactible format, with much less control unless there is another web kit command to pass a font size with a point or pixel value.

We changed this operation to match the spec:

I just did a little testing with the lastest nightly. You can set the font-size using .execCommand('FontSize' and values 1-7, but .queryCommandValue('FontSize') returns the font-size in pixels... 

Not consistent units! Is there a way to convert the result of .queryCommandValue('FontSize') to the corresponding 1-7 value in order to increment font size?

I think this bug should be reopened.  Comment #1 indicates that the behavior was changed to match Microsoft's spec.  The provided link is dead, but I believe the following link replaces it:

Based on the information in that spec, I should be able to specify 14pt or 14px (among a number of other types).  However, WebKit just converts these to -webkit-xxx-large.
