Debugger shows multiple versions of a shadowed variable in locals when running on the web

[nshahan]

When debugging with vscode.

main() {
  var x = 40;
  if (x > 10) {
    var x = 'hello';
    if (x.isNotEmpty) {
      var x = Duration.zero;
      print(x);
    }
  }
}

Observe the local variables in the debugger pane.

Web:

Getting the shadowed variable using expression evaluation works as expected though.
