Expected Result

In the type system: the object property in the TSESTree.MemberExpression type is a TSESTree.LeftHandSideExpression.

In the playground's tree: the object property on the first MemberExpression is an AwaitExpression. The second MemberExpression's object property is a NewExpression.

TSESTree.LeftHandSideExpression should therefore allow TSESTree.AwaitExpression and TSESTree.NewExpression.

Actual Result

The TSESTree.LeftHandSideExpression union does not include TSESTree.AwaitExpression or TSESTree.NewExpression.
