minimal pipleine example:

https://gist.github.com/LeoQuote/ef99eeb9d85ec72d0f23c7f7e40523ba/revisions

expect:
the failure steps will never be called when the first cell is succeed and other cells are failed

reality:
the failure step `echo you lost` was occaionally called when the first cell is succeed and other cells is failed

this can also happen when the post block is inside stages block.
