Terminal process remains on background and especially it occupies CPU resources excessively when after exiting terminal used as CMD.

When I use only PowerShell, terminal process disappears from background process list immediately after exiting terminal.

@dynalz commented on GitHub (Aug 12, 2019):

Indeed this happens to me aswell.
Some scripts I have on python have been running on background without my knowledge after closing out Windows Terminal. I saw them accidentally because logs were being written and I happen to notice.

Quite easy to test running any background process that opens up a port (node API or frontend web dev), in my case, after closing windows terminal http://localhost:8080/ keeps being accessible due to process never shutting down

This looks like another shade of #2232.
