[Bug]: FOW pathfinding quits "randomly"

[kwvanderlinde]

Describe the Bug

In certain simple sitations, the pathfinding around FOW just gives up and decides there is no path even though there obviously is.

To Reproduce

1. Open this campaign
2. Make sure the token movement does not reveal FOW:
   
3. As a GM, turn on player view (should also work by connecting as a player)
4. Attempt to drag the Elf to the marker.
5. At this point pathfinding shows "0" and no path.

Expected Behaviour

A viable path should be found as there is no obstruction.

Screenshots

This is the path that doesn't work:

Other spots work though:

Additional Context

I say "randomly" in the title because that's how it feels as a user. But it's not random at all - the same situation seems to always produce the same broken result. It's just not clear what exactly determines this case.
