Provide a confirm dialog instead of executing the revert operation directly

What steps will reproduce the problem?

1. show log of a repository
2. click the revert menu(I am trying to cherry-pick a commit from another branch, but click revert mistakenly)
3. you will found revert has been done, there is no chance to cancel the revert

What is the expected output? What do you see instead?
Expected:
When I click the revert menu, should popup a dialog to confirm the revert or let me cancel it

What I see:
There is no confirm dialog, and the revert has been done
