Comment:

 AFAICT this happens because the rewrite rules have already been registered
 when a plugin is activated for the first time. This type of timing issue
 is common in WordPress. I would recommend running `flush_rewrite_rules`
 the next page load after your plugin is installed.

 If that is incorrect, please provide a minimal, standalone plugin that
 demonstrates the issue.
