Uncaught TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'. in function NinePatchGetStyle, you may need to add try catch.. var computedStyle = window.getComputedStyle(element, "");

I have the same issue. Do you have any ideas, how to fix it?

rpendleton commented 7 years ago

I'm not sure if this was the source of the original issue, but it appears the example was encountering this error due to the use of a for...in loop over an HTMLContainer. I've pushed a commit that should fix that along with a few other issues.

I also experimented with adding a canvas element to the document and didn't see any problems, so I'm going to assume the for...in loop was the cause of the original issue as well.

That helped! Thanks!
