Incorrect quick fix for "use element access"

[DanielRosenwasser]

// @noPropertyAccessFromIndexSignature: true

declare let x: { y: { [x: string]: string } };

x.y.yadda/**/;

Request quick fixes here.

Current behavior*:

Quick fix is suggested for y, the code results in

declare let x: { y: { [x: string]: string } };

x["y"].yadda;

Expected:

Quick fix is suggested for yadda, the code results in

declare let x: { y: { [x: string]: string } };

x.y["yadda"];
