Hi Mathieu,

I guess the specification isn't clear enough regarding this. See bug
46289 [1], which contains a patch by Thomas to "fix" it and also links
to relevant discussions in the www-svg mailing list. :-)

Unclear or underspecified stuff usually leads to this sort of
unexpected incoherences among implementations... :-|


> So I would like to know if it's a bug of batik? Will it be fixed?

I'm not sure if the patch will be integrated. I'd vote for so, but I
remember the discussion somehow hit a dead end: there was no clear
consensus at the time... :-(  Maybe this is addressed in the second
edition of the SVG 1.1 specification. :-)

As stated, in order to "fix" it you may locally apply the patch
already referred. ;-)

As stated within the www-svg debate, another way of working around
this (in an inter-operable way?) would be adjusting the
"pointer-events" property [2] to "visible".


> Thanks a lot!

Hope this helps,
Helder
