I agree - it is an issue since the beginning and it'll be great if this
issues was approached for fixing, but it definitely wasn't fixed before or I
would've noticed ;)
Markus, do you think it's possible to create a dependency tables for all
query results which are checked upon page updates and invalidate the cache?
This will not completely fix the issue as query results might not contain
something which will be added when page is updated, although you can add
just property names to the dependency table so it always invalidates when
this property is updayed, but even partial solution will be good enough.
