autoplayAfterSeek has no effect

I have a scene with a video player, which all works fine.

However, when I click the forward or rewind buttons on the remote, the playback does not resume after seeking until I click the play button again.

I have

autoplayAfterSeek="true"

set on the Video node.

Anyone have any ideas what I might be missing?

This is happening with both HLS and MPEG videos.

Using a Roku stick on version 14.1

Thanks.
