EditContext: Should throw exception when Element.editContext is set to specific elements?

[masayuki-nakano]

I wonder, accepting EditContext with void elements like <br> and text control elements like <input> and <textarea> makes things complicated. Perhaps, setting editContext of such elements should throw exception?

That's good point. We'll work out a list of supported elements and add it in spec

I believe this was resolved in these issues: #19 #40. In https://w3c.github.io/edit-context/#extensions-to-the-htmlelement-interface we'll throw if the element isn't one of the supported ones.
