contenteditable inheritance behavior is inconsistent

When a parent element has contenteditable="true" and a child element has contenteditable="false", the inheritance behavior is inconsistent across browsers. Some browsers allow editing in the child, while others correctly prevent it. The behavior may also differ when the child has contenteditable="inherit" or no contenteditable attribute.
