Hi @fisker, @sosukesuzuki
Any news regarding this issue?

Hi @fisker, @sosukesuzuki, I really hate to pester, but this is causing some immense grief with having to manually remove the extra spaces after the markers, is there anything anyone can do to push this forward?

The deviation fights with basically every example and other linting tool out there as shown in a comment in #5019 which makes it a near impossible sell to match the other way round.
