Created attachment 275939 [details] Sample network pane view of multi download on cold cache You can notice this bug while looking at the Network panel in the Web Inspector on latest Safari 9 or Nightly. The SVG file is requested 5 times for 5 different fragment identifiers. It appears to be a Safari 9.3 regression. I am not seeing the problem on a 9.2 Simulator or older QtWebkit(s). See URL for repro and snapshot.

I am seeing this issue in Safari 9.1 and Mobile Safari 9.3 on iOS
Seems to be a 9^ regression, since I have the same behaviour in 9.1 (OSX 10.11.4) but not in Safari 8.0.2 (OSX 10.10.1).

This is pretty huge since our design system uses large sprites of our icons and the way they're currently downloading every time is a very big problem. I hope this will be prioritized and fixed quickly.

I think I found an additional bug... No SVGs are caching with an object tag: https://dl.dropboxusercontent.com/u/1256960/%20Research/JS/SVG_Parameters/dotObjectBug.html

I believe that is already a bug for this: https://bugs.webkit.org/show_bug.cgi?id=106180 But I don't see a caching issue <object data=".svg"> in 202569.
