The redstone block module does not stop items entering an inventory when activated, but does stop new items being extracted. Seems to be a bug.

This still appears to be broken, and shown on these images is the issue. In the images, items are going past a continually activated redstone block module.

I'm unable to replicate that, maybe it's a sync issue?

I'm on singleplayer.. so I don't think so, plus the chest fills up. Let me check again, just in case.

Yes, confirmed, the chest does in fact fill up when doing this in snapshot 86. Not sure how else to document this.. any ideas?

The items are already traveling when this happens, the redstone block module is enabled when after they start traveling.

I'm able to reproduce this now
