Steps to reproduce:
- create phriction document with visibility set to everyone (no login required)
- set default view policy of files to "logged in users"
- create document containing
```
dot {{{
digraph G {
thing1 -> thing2
}
}}}
```
Expected results:
non logged in users can see graph
Actual results:
non logged in users see broken picture
I suspect this generalizes to other policy default differences as well
