Using Kibana 7.6.1, when I open a Codex Index Pattern in the Discover Page the UI freezes and stops responding. No error messages.

hi @holt_g

what's a "Codex" Index Pattern?

This seems to be a bug, and I would log here [https://github.com/elastic/kibana/issues/new](https://github.com/elastic/kibana/issues/new) . Adding steps to reproduce this issue would be really helpful.
