---------------------------+-----------------------------
 The plugin endpoint `/wp/v2/plugins/(?P<plugin>[^.\/]+(?:\/[^.\/]+)?)`
 added in 5.5 breaks JavaScript parsing of the regular expression.


 This can be tested by adding the following into the console:
 `new RegExp(/^[^.\/]+(?:\/[^.\/]+$/);`

 Which results in:
 `VM90:1 Uncaught SyntaxError: Invalid regular expression:
 /^[^.\/]+(?:\/[^.\/]+$/: Unterminated group at <anonymous>:1:1`


 One of the effects is that the node-wpapi library can no longer
 autodiscover WordPress endpoints: https://github.com/WP-API/node-
 wpapi/issues/476
