Did anyone file an issue on the polyfills? We're not going to be aware of issues on Firefox's bug tracker...
Also, that's an old version of the polyfills, before Polymer 2.0, it might have been fixed on our end quite a while ago.
https://bugzilla.mozilla.org/show_bug.cgi?id=1256031 has an example of a page using polymer that runs into this problem.
