Recently I have been considering using Polymer elements in a project I am working on. However, I am unable to see any elements being rendered in the new beta version of safari for OS X 10.10 Yosemite. I completely understand that Yosemite and Safari are currently in the DP phase, but I am curious as to why the new verison of Safari has broken compatibility with Polymer elements (I can confirm Polymer elements work in Mavericks version of Safari).
I was able to open the developer console and spot an error. I am unable to reach the exact error at this time, but I know the error was at patches-mdv.js at line 57, claiming a Read Only error.
I just tested the Polymer Project website on my iPhone with iOS8, having the same results.
Does anyone have an idea on what I could do to fix this issue temporarily until the Polymer-Project team fixes it?
One apparent problem is that the Safari beta has at least one low-level property accessor (specifially
HTMLBaseElement.prototype.href) that is misconfigured from the standard.
So, cursory investigation implies this is a bug in Safari, not Polymer.
