The HTML living standard defines the indeterminate property for checkboxes. It cannot be set using an HTML attribute though, only through JavaScript. Currently, the choo DOM diffing does not respect this property.
I have added test cases for the checkbox and disabled properties as a separate commit, since I expected them to behave similar to indeterminate. However, attempting to allow setting the property like <input type="checkbox" indeterminate=${false}> does not do the expected thing and would still set the property to true.
