Changing gradient stop does not trigger redraw of referencing elements

What steps will reproduce the problem?
hello,

this seems like it should be simple but i am stumped. i've created a
simple test case below to illustrate my problem. i do not seem to be
able to modify stop-color or stop-opacity values of svg inside an
OBJECT element for ie+svgweb

i'm using contentDocument as described in the svgweb user manual.
script works fine in other svg supporting browsers. i've tried
both .setAttribute('stop-color', color); and .style.stopColor = color;
methods to no avail. any help would be greatly appreciated.

thanks for your ongoing work with this excellent project.

What is the expected output? What do you see instead?
Clicking the links should change the stops. They do not.
