the docs https://plugins.jenkins.io/throttle-concurrents/ state:
Throttle this project as part of one or more categories
- With this option the Maximum Total Concurrent Builds and Maximum Concurrent Builds Per Node fields are ignored.
however the help '?' text for the "Maximum Concurrent Builds Per Node" field states:
The maximum number of concurrent builds of this project (or category) to be allowed to run per node.
so, which is it? is it ignore when category-throttled, or not?
