After checking your report and trying your test case with IE9RC I can only partially reproduce your issue.
With this test case I verified that passing
.css() both work when reading. And that passing
msTransform actually doesn't work.
curCSS() which in IE9 is
getComputedStyle and thus actually looks for
computedStyle.getPropertyValue( name ) (where name is
The output when accessing
matrix(1, 0, 0, 1, 10, 10) in both cases. When accessing
msTransform no value is returned.
Although when you try to set a value via
MsTransform fail and
msTransform works. As internally
style[ name ] = value is done (where name is
MsTransform). But providing a set-cssHook for
MsTransform makes it possible to workaround this issue (see my test case).
So I think this is a non-issue, will close if you confirm.
