Room history does not show creeps entering the room

[SystemParadox]

I've noticed that the room history doesn't show creeps entering the room properly. The creep is invisible whilst on the exit tile, and suddenly appears in their next position (with no move animation) when they move off the exit.

For example, see https://screeps.com/a/#!/history/shard3/W39S27?t=8188729. The towers heal an invisible creep which then appears the following tick.

I'm pretty sure this used to show correctly, perhaps before the recent WebGL updates.

Thanks.
