When I open a pull request on a branch in my repository in gitea, a pipeline step is responsible to check if the pull request title is according to the specification. Until now this check was only activated for commits and worked fine by using the $DRONE_COMMIT_MESSAGE variable.
While testing in a separate repository I noticed that the $DRONE_COMMIT_MESSAGE is set to the pull request title, when the PR description is empty. As soon as the PR description is set, the $DRONE_COMMIT_MESSAGE contains the full PR description.
Is there any way to change that behaviour, in order to always receive the PR title in the variable? Or is there any other variable I might have missed, which always has the PR title?
