Description
Using tile-cover on [Fiji](https://gist.github.com/lily-chai/7bb94de0b3b005c615faafbcd9d8293a) at `{min_zoom = 4, max_zoom = 4}`, I got
```
[ [ 0, 8, 4 ], [ 15, 8, 4 ], [ 16, 8, 4 ] ]
```
`[ 16, 8, 4 ]` is not a valid z4 tile.

Research direction
Start by reproducing the Fiji example from the linked gist with tile-cover at min_zoom 4 and max_zoom 4. Trace how the longitude at 180 is converted into tile coordinates; done means the result no longer includes the invalid z4 tile [16, 8, 4].
