Animating non-px units, accordion fillSpace issue

Animating non-px units, accordion fillSpace issue


So http://dev.jqueryui.com/ticket/4695#comment:4 is still open, the
visual testcase fails due to the relative (em) units for inline
paddings: http://jquery-ui.googlecode.com/svn/trunk/tests/visual/accordion/accordion_option_fillSpace_true.html
Replacing those units with px values fixes the issue perfeclty in FF
(still small jumps in IE and Safari). The accordion could overwrite
the em-values and use px instead. Or ignore the issue and try (and
fail) to animate em. Whats the better approach? How important is
support of relative units?
