Video with Lightbox ON: In pageflow shows only box in overlay color but no video

Reproduction:

1. Insert a Greenshift video block.
2. The video is shown correctly and with its native aspect ratio (since 6.6.2). The default initial options are: Player Controls ON, all other options OFF.
3. Activate option ?? Enable Overlay or Lightbox.
4. This now reveals the second option ? Enable Lightbox. Also enable this one.
5. In the Block Editor the video within the pageflow is shown, with the default overlay (purple, 0.5 opacity).
6. Save and reload in Frontend.

Expected: When I scroll the page, the video in the pageflow is shown with its first frame and the overlay color (e.g. purple, 0.5 opacity). As soon as I click it it opens in a larger lightbox and autoplays.

Actual: In the pageflow it is just shown as a rectangle with the overlay color, but no video content (of the first frame) at all. When clicking it in the Lightbox it shows and plays correctly.

Workaround attempts — None worked:

• Overlay color cleared entirely. The box color just changes to light grey.
• I added a media fragment #t=0.001 to the video src URL. Did not help either.

Maybe the Lightbox feature is supposed to only work in a video block which has a placeholder image? Mine has NO placeholder image. I had hoped it uses the same video file twice. Once in the pageflow and once in the Lightbox.
