[🐛 Bug]: /opt/bin/video.sh: line 135: wait: pid 48494 is not a child of this shell

[MJB222398]

What happened?

I have a docker selenium grid with a Hub, and four each of Chrome, Edge, Firefox nodes, and then a separate video container for all of these 12 nodes. A new video is recorded for each driver session and the name of the video file is just the session ID. Today I had the video take 4 seconds to stop recording after the web driver session was stopped. When I looked in the logs for the video container I could see there might be an issue:

/opt/bin/video.sh: line 135: wait: pid 48494 is not a child of this shell

Command used to start Selenium Grid with Docker (or Kubernetes)
