Yes, that's true :(
@andrerom should I cherry-pick this commit on 1.5 branch or is there a more proper way?

[andrerom]

not a big must as 1.6.0 is soon here, but you can do that, just in case we do a 1.5.2 update to sales demo and/or platform.sh, but make sure to merge 1.5 into master so they stay in sync.

@andrerom I was wrong. This commit should belong to master only as it fixes issue with blog_post preview but after implementing QueryTypes (added in 1.6).

This one here 91a2c13 fixes same issue but before QueryTypes. So partially it's related (fixes same template) but should stay on master at this moment.

Description was misleading, sorry for that.
