We use GitHub PRs as conditions to build prerelease version of our applications using the following pipeline clause:

{{when { changeRequest() } }}

However, if we create the pull requests as draft pull requests (a nice feature for in-progress work), Jenkins does not detect the PR or create any build for it.  We have enabled the traits below, but I cannot find any hints regarding draft PRs:

<traits>
<org.jenkinsci.plugins.github_branch_source.BranchDiscoveryTrait>
<strategyId>1</strategyId>
</org.jenkinsci.plugins.github_branch_source.BranchDiscoveryTrait>
<org.jenkinsci.plugins.github_branch_source.OriginPullRequestDiscoveryTrait>
<strategyId>1</strategyId>
</org.jenkinsci.plugins.github_branch_source.OriginPullRequestDiscoveryTrait>
<org.jenkinsci.plugins.github_branch_source.ForkPullRequestDiscoveryTrait>

<trust class="org.jenkinsci.plugins.github_branch_source.ForkPullRequestDiscoveryTrait$TrustContributors"/>

<org.jenkinsci.plugins.github_branch_source.TagDiscoveryTrait/>
</traits>
