So this seems to be a problem with `document.cloneNode` which Polymer uses when it stamps out its templates.
You can reproduce it here: http://jsbin.com/tuwuco/1/edit?html,output Set your devtools to a device pixel density of 3, refresh the page, and hit the 'run with js' button. Chromium bug is here: https://code.google.com/p/chromium/issues/detail?id=446574 In the short term you can work around this by using vanilla custom elements/shadow dom and using importNode instead of cloneNode. But I think this should hopefully be fixed quickly. On Tue, Jan 6, 2015 at 9:06 AM, Rob Dodson <[email protected]> wrote: > I'm looking into this. Seems like their may be a bug.
