C.J Ku: Robert thinks this patch will fix bug 1352979 and looking at the patch, it might. Could you try out attachment 8853960 [details] so we can dupe it?

Is resolving <use xlink:href="#local"> like this what we should be doing? The reason we do it for url(#local) values in CSS properties, IIRC, is because it makes it difficult to reference resources in the main document when url(#local) is specified in an external style sheet, which is why the wording in https://drafts.csswg.org/css-values-3/#local-urls was added. As far as I know (though I didn't check) we don't have any spec wording requiring this for <use xlink:href="#local">. Do other browsers do this? If they do we should probably do it and make sure a spec requires it. If they don't, then I'm not sure we should, although I'd be happy to hear arguments we should.

There are some discussion in bug 1352979, in summary: 1. discussion thread: https://github.com/w3c/svgwg/issues/61 Although, there is a contradiction between svg 2 spec and css-value spec currently. (Please refers to the latest comment, written by Robert, in this thread) 2. The reality chrome and safari: had resolve against current doc Edge: will resolve against current doc(https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/11490803/)

This seems to be broken again in FF 61 (also in the beta of 62): https://codepen.io/wvankuipers/pen/rZjyGW (broken: with base) https://codepen.io/wvankuipers/pen/eLgRpb (working: without base)
