UI shifts to the left and gets cut off when making an amend (when using floating window)

**Bug**
When I amend a commit, the lazygit UI shifts to the left and gets cut off (when using a floating window in neovim).

**Steps to reproduce the behavior:**

1. open lazygit in a floating window in neovim
2. amend a commit
3. observe the UI shifts to the left and gets cut off

**Expected behavior**
The UI should not shift to the left when amending a commit
