Is this PR really correct? If I try to add <div [contentEditable]="{{isEditable}}"></div> in the tutorial editor, I get an error:

I think interpolation and binding are mutually exclusive? Either use [] to bind an expression to a property, or use {{}} to have dynamic parts in a string.

<div contentEditable="{{isEditable}}"></div>
<div [contentEditable]="isEditable"></div>

Yes, a fix already is already pending #60725.
