Thank you for your patience with the review process. This PR is looking pretty good. Have you tested it with a normal Linux build to make sure nothing has broken there?
Once the merge conflicts and comments are addressed I think we can merge this to master. I'm working on a Chromium update currently so there might be one more round of merge conflict resolution before that point.
Thanks for showing interest to merge it,
I have addressed all your comments , rebased with latest cef to avoid conflicts, and also did some more cleanup, like removing extra manifests.
For all the patchset I have been testing with linux build on x11 to avoid any regression,
I think it would be good to have final look from again
