Describe your question, feature request, or bug.

Using Leaderf --popup buffer , any help buffers are not present . Those are the buffer found by help. I understand that :buffers doesn't display them as well. I have countless of times reopened buffers because of this. They do have buffer number.

Steps to reproduce

1. :help winid
2. Leaderf --popup buffer

Actual behaviour

can't find help buffer

Expected behaviour

To be found.

Interesting . It does work with Leaderf window . However, it doesn't solve the issue.
