Cron-configuration in Jenkinsfile ignored when obtained via Remote Jenkinsfile Provider plugin?

[demo-cicd]

Describe the bug
Build is not triggered at expected time, even though Jenkins shows the time-based trigger in the GUI correctly: H H(16-18) * * 0-5
We suspect that this is ignored since the Jenkinsfile needs to be obtained from Git by the plugin first before it can be interpreted.
Push-based triggering works fine though.

To Reproduce
Steps to reproduce the behavior:

1. Create a Jenkinsfile with a 'triggers'-section containing a 'cron'-statement
2. Upload Jenkinsfile to a Git-repo
3. Configure a build to use the Remote Jenkinsfile Provider plugin to obtain the Jenkinsfile from the Git-repo
4. Wait until build is triggered at expected time - which won't happen

Expected behavior
Build triggers at times specified in Jenkinsfile.
