### Describe your issue

when i open a org-roam node, the opened buffer sometimes gets a path relative to the project directory i was in when invoking `org-roam-node-find`.

the buffer name is not `~/org/zettel/1234-bla.org` but rather `some-project/../../../../org/zettel/1234-bla.org`.

- `(projectile-project-root)` in that buffer correctly gives `/home/me/org`

### Steps to reproduce

be in a project buffer
open a roam node
