The shadow DOM spec doesn't specify how the "title" attribute works. According
to https://html.spec.whatwg.org/#the-title-attribute, the "title" attribute
would not inherit in shadow DOM.

It's important that the "title" attribute inherits in shadow DOM wrt to the
composed tree. Currently, it's impossible to create an element with shadow root
and set a tooltip on it by setting the "title" attribute on the host element.
