Description

We are heavy flow users and are on flow 0.54.0, so I assume this may be related to @jseminck's changes in #1400. This may be an entirely new case or separate bug.

It appears to be failing when visiting IntersectionTypeAnnotation:

prop-types_js_-material-ui-___projects_material-ui

How can I help narrow this down further?
