Expected Behavior

Expected behavior is:

1. The scene I set as the current program becomes the current program
2. The scene I set as the current preview becomes the current preview.

Current Behavior

The Current behavior is:

1. The scene I set as the current program becomes the current program
2. The scene I set as the current preview is completely ignored and the preview is whatever was the previous current program.

Steps to Reproduce

1. Have 4 scenes: Scene A, Scene B, Scene C, Scene D.
2. Have Scene C set as the current program, have Scene D set as the current preview.
3. Run either of these two pieces of code.

    await obs.call('SetCurrentProgramScene', {
      sceneUuid: UUID_SCENE_A,
    });
    await obs.call('SetCurrentPreviewScene', {
      sceneUuid: UUID_SCENE_B,
    });

    await obs.callBatch([
      {
        requestType: 'SetCurrentProgramScene',
        requestData: {
          sceneUuid: UUID_SCENE_A,
        },
      },
      {
        requestType: 'SetCurrentPreviewScene',
        requestData: {
          sceneUuid: UUID_SCENE_B,
        },
      },
    ]);

4. Observe that Scene A is CORRECTLY set as the current program
5. Observe that Scene B is NOT set as the current preview after this code runs.

Anything else we should know?
