When launching pipelines on merge requests from Gitlab, Jenkins creates a pipeline for the source branch in the project pipeline list.
For example, there is an open merge request from the testdev branch to the dev branch.
Creating a commit in branch testdev
Gitlab runs job jenkins via a web hook and creates an external pipeline,
but it is shown as a commit to the testdev branch, not as a merge request.

in the correct case, ref points to MR (refs/merge-requests/1274/head)
In the settings of the gitlab webhook, only the event from MR is set, in the settings of the jenkins job (gitlab-plugin) it is set to accept MR, the trigger for push events is disabled.
The expected result is to get a pipeline display with the merge request attribute from Jenkins.
