Placeholder for openshiftio/openshift.io#

@amisevsk could you take a look?
Is this a regression? I don't recall making any changes around this recently.
Yes, it's regression.
This issue reproduces in upstream 7.0.0-beta-3.0 as well.
Created issue https://github.com/eclipse/che/issues/13218 to track
I took a brief look at fixing this issue but couldn't figure it out so I'm leaving it for normal prioritization (unless it's a blocker @AndrienkoAleksandr )
Editing the workspace config works without any problems, but making any modifications to the machine recipe results in the recipe being thrown away with some errors logged (see upstream issue).
I't's not a blocker issue.
Closing in favour of https://github.com/eclipse/che/issues/13218
