As the number of commits that need to be interactively rebased grows, the GUI underneath for context/filnames/commit message shrinks. If enough commits are selected (30+?) only the bottom buttons are displayed. and no scrollbar appears to be able to scroll through commits. In addition you cannot drag the UI to resize it to bring back the bottom UI elements if you select a large number of commits. To make everything but the bottom buttons dissappear entirely I had to select ~ 60 commits however this may be resolution dependant.

Steps to reproduce:
*Create a repo with > 60 commits
*Attempt to interactive rebase near the start of the repository.

Expected behaviour would simply allow scrolling inside the top window without the UI for commits expanding at all.
