This was fixed in the following CL: https://codereview.chromium.org/2421683002/ and has been in Canary for a few days now.

We would like to merge this change into M55. It is a two-line change that adds a command-line flag when launching the CCT (chrome cleanup tool) and I have tested that it works on the Canary channel.

Is this change applicable to all OS or any specific OS?

This is a Windows-only feature.

Your change meets the bar and is auto-approved for M55 (branch: 2883)
