No messages when filtering to a station that has a timestamp

[sudonhim]

I have stations added with timestamps, e.g. ~samzod/urbit-meta/~2018.2.26..04.05.58..7dbf

If I filter to these in the web UI, I get no messages. It looks like the filtering should be ignoring this timestamp:

Discussed in meta, but for the record:
It's probably using the path found in the inbox's sources directly. It should be stripping off the subscription details instead and operating on just ~ship/circle, for the filtering case.
