List projects API only returning projects user is member of

According to the List projects API docs, GET /projects returns a "list of projects accessible by the authenticated user" however it is only returning a list of projects the user is a member of and not public projects they are not a member of.

Steps to reproduce

On GitLab.com use the GET /projects API endpoint

Expected behavior

GET /projects returns list of projects accessible by the authenticated user including public projects they are not a member of.

Observed behavior

GET /projects only returns a list of projects the user is a member of.

Workarounds

Iterate over each project using GET /projects/:id
Search using GET /projects/search/%25
