Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/601.7.8 (KHTML, like Gecko) Version/9.1.3 Safari/601.7.8 Example URL: see attached reduction Steps to reproduce the problem: 1. Unpack attached reproduction 2. cd $wherever_you_unpacked_it 3. python2 -m SimpleHTTPServer 4. open http://localhost:8000 5. Resize the browser window below and above 767px to trigger the bug What is the expected behavior? * The console should not show that unload is called again * The gage-pointer should not disappear What went wrong? * The console shows that onload is called multiple times * The gage-pointer disapears Does it occur on multiple sites: Yes Is it a problem with a plugin? No Did this work before? N/A Does this work in other browsers? No Safari (Version 9.1.3 (11601.7.8) and Technology Preview Edition Release 12 (Safari 9.1.2, WebKit 11603.1.3)) Chrome version: Version 51.0.2683.0 (64-bit) Channel: n/a OS Version: OS X 10.11.6 Flash Version: The problem is that the state that is in the SVG is lost. This is especially problematic if it is changed because of user interaction. The workaround to this is to also save the state of the SVG somewhere outside of it, and then reapply it whenever onload is called on it again. This is quite a PITA.

Thanks for the report! My guess would that when the MQ trigger, we need to reattach the <embed>s layout object - which loses the frame/SVG. Not really an SVG issue as such, but probably in the HTMLFrameOwnerElement/HTMLPluginElement/HTMLEmbedElement complex. Randomly punting to one of the HTML components for more triage.

Julien's no longer with the project. I don't really know who should own this, but I suspect the fix will need to do something smart for LayoutObject reattachment for LayoutSVGRoot, etc. Some custom attachLayoutTree/detachLayoutTree for HTMLObjectElement, SVGSVGElement, etc.
