It’s intended behavior. The reason is that the command should not be able to run and possibly edit the document simultaneously while the user is editing the document.

The solution is to run the command in the background/daemonized. See this post for an example [1].

My I ask why you’re creating a new RuboCop bundle when this one [2] exists?
You might also want to take a look at this pull request that adds a RuboCop formatter command to the Ruby bundle [3].
