Created attachment 379146 [details] svg-filter-href Open the attached test case. Result: One green rectangle. Expected: Two green rectangles. The first rectangle is a <rect> element with a filter whose id is "filter". This filter is drawn correctly. The second rectangle is a <rect> element also but with a chained filter. The chained filter is defined as "<filter id="chained" href="#filter"/>". This chained filter does not work as expected.
Just to update - Safari 16.2, STP161 and Chrome Canary 111 all show just one green rectangle while only Firefox Nightly 111 show 'two' green rectangle. Thanks!
