### Problem
Cancelling import of projects that are pending or in progress has been implemented in https://gitlab.com/gitlab-org/gitlab/-/issues/364783+ and https://gitlab.com/gitlab-org/gitlab/-/issues/247325+.
[Comment](https://gitlab.com/gitlab-org/gitlab/-/issues/247325#note_991372298) points attention to other places the cancel functionality could be added:
- Import history page includes currently running imports as well.
- If you navigate to a project when it is importing a page is displayed (project view page).
### Proposed solution
We could embed cancel functionality on those pages as well.
