JavaScript debugger is using a phantom stack frame to delineate await
points; that frame reuses a frame ID of 0, which collides with other
frames returned from that adapter.

https://github.com/microsoft/vscode-js-debug/blob/934075df8c3c9726ead99aa8ee6815b36d835c34/src/adapter/stackTrace.ts#L287

The bug has since been fixed in
https://github.com/microsoft/vscode-js-debug/issues/2234, but we'll need
to wait for a new release of node debugger for that to make a
difference. Until then..

Release Notes:

- Fixed a bug with JavaScript debugging which led to stack trace list
containing excessive amount of `await` entries.
