A dev tool to preview what an item would look like in a different zone!
To use, open the browser console, and type `DTIHackLayerZone(layerId, zoneIdOrName)`, but replace `layerId` with the layer's DTI ID, and `zoneIdOrName` with either the zone ID or its name in quotes.
This happened in an earlier change too, I forget where, but there's some compiler bug that causes comments placed in this kind of spot to yield this error in production, but not in dev:

Oh well, moved the comment!
This was a surprisingly big win! Item is heavier than it looks, because it has like 6 Chakra components, which aren't expensive but aren't _cheap_ in a re-rendered list that needs to be fast, you know?
And it's even more important on search, where there's a lot of items on the page. (we should virtualize it too but that's a thing for another day)
One fix was that `position: absolute` stuff was appearing over the drawer, including the item search clear button, oof!
Another fix was for a weird bug(?) in Apollo Client, see comments
