827039 - MathML operators ignore text shadow

Status: NEW

(Core :: MathML, defect)

Attachment: MathML shadow test case

I have a globally set text-shadow on my HTML. THe text shadow is carried over correctly to all MathML elements, except for operators (everything inside `mo` elements) and implicit symbols created by e.g. `mfenced` elements.

I also tried setting the text-shadow directly for the `mo` elements, but the property is completely ignored (other properties work as expected).

This might be related to bug 759462, as that one is also about different behaviour for `mo` elements.

A test case is attached.

Yes, as in bug 759462 the relevant elements to look at are:

https://hg.mozilla.org/mozilla-central/rev/ff353339df3

This includes <mo> characters drawn with nsMathMLChar, fraction bar/slash, root bars and menclose graphical elements.

One will have to use the appropriate GetStyle* function to get the shadow style but the complicated part will be to implement the drawing of the shadow...
