## Description of the bug
Light fixtures on a tile prevent getting on a table from the corner but not the vertical. Tables without light fixtures allow table vaulting from the corner.

## What's the difference with what should have happened?
Lights on the wall should not block movement freedom in any way.

## How do we reproduce this bug?
1. Crawl on a table from a vertical or horizontal.
2. Crawl on a table from the corner that also has a light fixture in its tile.
3. Flop on the ground in failure.

## Attached logs
```

The light fixture prevents you from climbing the table.
