`git start` doesn't abort rebase

[fish-404]

In Exercise fix-old-typo, I try to use these commands to solve the exercise, after I find it doesn't work, I want to restart but doesn't work.

Environment: I run this repository in Gipod and use the environment to exercise

vim file.txt
# then edit the file
git commit -a --fixup=amend:<commit>
# then edit the commit 
git rebase -i
git start fix-old-typo
# see the start info but not cancel the rebase and the branch is `fix-old-typo|REBASE 1/2`

# try to start other exercise to test
git start commit-lost
# see the start info but not cancel the rebase and the branch still `fix-old-typo|REBASE 1/2`

# then use git rebase --abort get reset status 
git rebase --abort
