-// - A ScriptPromiseResolver retains a ScriptState. A caller |
-// can call resolve or reject from outside of a V8 context. |
-// - This class is an ActiveDOMObject and keeps track of the associated |
-// ExecutionContext state. When the ExecutionContext is suspended, |
-// resolve or reject will be delayed. When it is stopped, resolve or reject |
-// will be ignored. |
