Ps: it works in firefox 170541 1 ap 2009-12-10 15:03:12 -0800 One workaround is to use <img> instead of <object>. 170634 2 ap 2009-12-10 21:22:15 -0800 It's is broken due to this code in MainResourceLoader::continueAfterContentPolicy(): if (status < 200 || status >= 300) { bool hostedByObject = frameLoader()->isHostedByObjectElement(); frameLoader()->handleFallbackContent(); // object elements are no longer rendered after we fallback, so don't // keep trying to process data from their load if (hostedByObject) cancel(); } A response generated in MainResourceLoader::handleDataLoadNow() from substitute data has status of 0, so the substitute data is not used for OBJECT. 170635 3 ap 2009-12-10 21:29:13 -0800 This code was added in <http://trac.webkit.org/changeset/13615>. 248979 4 zimmermann 2010-07-09 07:17:02 -0700 Changed component to SVG, so it shows up in my all-svg-bugs search. 249078 5 ap 2010-07-09 10:12:15 -0700 This is not really about SVG, it's a general issue with OBJECT and appcache. 360408 6 michaeln 2011-03-01 17:06:57 -0800 This looks like it may be related to https://bugs.webkit.org/show_bug.cgi?id=55500 403613 7 ap 2011-05-13 09:52:26 -0700 This is related, but is not a duplicate. The additional problem here is that SubstituteData doesn't even have a field for response code, so we don't pass it from ApplicationCacheResource to MainResourceLoader. This should be a very easy fix. 1896039 8 ahmad.saleem792 2022-09-03 10:31:08 -0700 I changed the test case from Comment 0 into JSFiddle: Link - https://jsfiddle.net/2fmvz7da/ Only Firefox Nightly 106 show "Image" while other Chrome Canary 107, Safari 15.6.1 and Safari Technology Preview 152 does not show SVG inside object. Just wanted to share updated testing results. Thanks! 1896040 9 ahmad.saleem792 2022-09-03 10:32:20 -0700 Just to update - my testing can be wrong because I didn't test it in offline mode. Thanks! 1896204 10 ap 2022-09-04 13:38:20 -0700 Once an appcache is saved, it intercepts loads even when online. So in a correct test, the SVG will show up the very first time, but not after that. This JSFiddle is not a correct test, as this issue is about subresources that are part of appcache, and are loaded separately from the main resource.
