I have a pull-requests section in my `bitbucket-pipelines.yml` file defined line so:
pipelines:
pull-requests: '**':
- step:
... lots of steps...
When I open a pull request between two branches of my repository, a build is triggered as expected. But when someone opens a build from a fork of my repository back to my repository, no build happens.
Am I missing some configuration necessary to make this happen, or is it not yet supported?
