You'll need to raise an issue at https://github.com/chromiumembedded/cef/issues (post a link back here for reference).

Will need to be fixed in CEF.

As a short term workaround try reverting back to the alloy bootstrap. See #4835 (comment)

Closing as upstream.

Looks like you already opened chromiumembedded/cef#3739

CEF no longer supports that argument with the Chrome Bootstrap.
