I just upgraded from beta 4 to 0.10.0 final and it now longer renders HOT at all.
reverting back to beta 4.
I hacked the code to change:
var counter = Date.now() % 1e9;
var counter = 0;
and it works now.
Care to explain this mod logic? I don't see the point of it.
This bug comes from WeakMap shim made by authors of Polymer librarary. It seems, that counter variable is used for creating a unique WeakMap name, however I haven't studied the entire shim code, so I'm not 100% sure if your hack will make a difference.
The solution provided by @geins in #1252 seems to be more appropriate.
Bugfix #1251. Fixed WeakMap shim for IE8
Hack as outlined in #1252 seems to work.
Merge branch 'feature/bugfix-#1251' into develop
This is fixed now in 0.10.1. Could you please try again?
