Expected and unexpected behavior in a project
It seems the issue manifests when there's only one instance of a shadowTree displayer with the offending SVG, except sometimes when the shadowTree is not the first child in the document that contains the offending SVG...

reduced test case
A reduced test case is attached.
I am able to reproduce this bug in WebKit ToT / Safari 16.5.1 as well. Chrome Canary 116 and Firefox Nightly 115 works fine. Created attachment 466820 [details]

Created attachment 401145 [details] Repro filter:url(#myFilter), fill:url(#myPattern), etc. can fail in some circumstances when the SVG is in a shadowTree and there are multiple shadowTrees with that SVG in it. The result is no fill, no filter or the element disappearing. The attached example reproduces in Safari 13.1, STP 107, and iPadOS 13.5. It does not reproduce in Chrome 83 or FF 77.
