isOpen attribute of Details does not work

[Frizlab]

Or more precisely it only works when set to true.

Here’s the spec: to have the details element close, the open attribute must be fully removed: https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/details#open. Currently it is set to value false, which explicitly does not work.

Yup, you are right. I stumbled upon the issue too. It will be resolved by #207.

It went live with alpha.15. I am closing the issue.
