Expected Result

In the type system: theobject property in theTSESTree.MemberExpression type is aTSESTree.LeftHandSideExpression.

In the playground's tree: theobject property on the firstMemberExpression is anAwaitExpression. The secondMemberExpression'sobject property is aNewExpression.

TSESTree.LeftHandSideExpression should therefore allowTSESTree.AwaitExpression andTSESTree.NewExpression.

Actual Result

TheTSESTree.LeftHandSideExpression union does not includeTSESTree.AwaitExpression orTSESTree.NewExpression.
