Summary

User Interface behavior is different between the "Created" tab and the "Reviewing" tab of your personal Pull-Request dropdown panel.

The "Reviewing" tab's list does not scroll and the panel will grow to the needed size (up to a maximum size based on window size) to view all PRs concurrently whereas the "Created" tab panel will stop at a max of 7 and then gain a scrollbar.
In the case of large amounts of PRs in both tabs, You can scroll through and see all "Created" PRs but you will be unable to list all "Reviewing" PRs.
