Simulator nolonger updated according to modified codes, after “Build Project for Hardware”

Hi, Richard Knoll (@riknoll) and Joey Wunderlich (@jwunderl)
I met a issue:
Simulator nolonger updated according to modified codes, after “Build Project for Hardware”

Reproduce:
open any project with Makecode extension for VS, click “Build Project for Hardware”, then choose whatever a HW.
Modify source code, then project re-build automatically.
Project in simuator still previous edtion before, and no longer update unless close/reopen VSCode.

Browsed source, looks like:

vscode-makecode/src/web/extension.ts

Line 361 in a479713

Simulator.currentSimulator.simulateAsync(await readFileAsync("built/binary.js", "utf8"));

• Simulator always load binary.js from build/binary.js
• But “Build Project for Hardware” updated BuildOption, then redirected path to build/HW/binary.js. And “Build Project” compiled for that HW only after that, and then only build/HW/binary.js be updated.
