Display Locking

This feature locks a DOM element for display. When an element is locked, its visual representation on the page does not change as a result of DOM mutations. Instead, the DOM is mutated and its structure can be inspected and modified in script. When the lock is committed, the user-agent presents content without jank. This allows the developers to develop widgets that do not jank the page even if their layout is expensive.
