Dead code after return statment isn't removed during minification

[fa93hws]

/* eslint-disable */
function spyReport(event) {
  if (true) return;
  if (!globalState.spyListeners.length) return;
  const listeners = globalState.spyListeners;
  for (let i = 0, l = listeners.length; i < l; i++) {
    listeners[i](event);
  }
}

spyReport(asdf);

is minified to

(()=>{function n(s){return;if(!globalState.spyListeners.length)return;for(let e=0,l=t.length;e<l;e++)t[e](s)}n(asdf);})();

while it should be

(()=>{function n(s){return;}n(asdf);})();

How to reproduce?

create any.js which have the following content

/* eslint-disable */
function spyReport(event) {
  if (true) return;
  if (!globalState.spyListeners.length) return;
  const listeners = globalState.spyListeners;
  for (let i = 0, l = listeners.length; i < l; i++) {
    listeners[i](event);
  }
}

spyReport(asdf);

build it with esbuild any.js --bundle --minify --outfile=any.dist.js

esbuild version: 0.8.7
node version: v12.16.1
OS: macOS Catalina 10.15.7

Thanks for the report. It looks like control flow liveness is not propagated to subsequent sibling statements. I'll fix this.
