[internal]: vscode debugging is broken in unreleased version

[mxschmitt]

Not possible to debug todomvc after microsoft/playwright-vscode@4328be9

Repro: Set a breakpoint in should allow me to add todo items and try to debug it.

Note:

      this._vscode.debug.onDidTerminateDebugSession(() => {
        debugEnd.cancel()
      });

is getting called and causing the debugging session to end.

Whew, good job catching this! I've investigated and it seems that our main debug run spawns multiple "debug sessions" underneath. The child process that's used to evaluate the config gets its own "debug session", and as it sucessfully closes the session calls onDidTerminateDebugSession. I'll see if we can limit this to only listen for the main debug run.
