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. In Chrome, available with Display Locking flag enabled (in about:flags)
