Trouble with ignore_in_feed

[Mikael Nilsson]

Using latest venus, I want to disable posts jumping to the top when
updated, so I found advise in an old post on this list, to set

ignore_in_feed: updated

in the [Planet] section.

While it seems to work (it disables the jumping), it also brings with it
a serious issue: All items in a newly added feed is given a time stamp
of "now", completely ignoring their published date as well. I don't
think that's the intention, and it's certainly not what I was
expecting. 

Is there a fix?
