When you look at the monstar while Casey is talking at around 1:05:36 then you see a clear sortbug that the Monstar is sorted above the stairs topmost step where he/she clearly shouldn't be.

(Could be fixed in 311, haven't watched that yet)

Much like I discussed already regarding the hero sorting against the stairs, until we finish the Z work and stop having the stairs be X-shifted, we can't make any conclusions about sorting against them.
