I have a multibranch pipeline, connected to GitHub repository, which triggers on comment added to PR page in GH.
Same pipeline can execute on dev and prod branches.

Jenkinsfile specifies throttle setting, that allows max 10 parallel build across all PR and branch jobs (with usage of category throttle)

Problem is that, when I start build manually ("Build", "Build With Parameters", "Rebuild"), throttle option is respected (as in below image)
When trigger comes from GitHub (comment added to PR page), throttle is not respected, and there will be as much builds on different PRs, as there was events.

When limit is set to 10, and there will be 12 comment events from GH and I start build on branch manually, this intormation is displayed.
