Pipeline Clone param not working

I tried to clone an existing pipeline https://buildkite.com/llvm-project/bazel-rbe by going to https://buildkite.com/organizations/llvm-project/pipelines/new?clone=bazel-rbe, but no fields were pre-populated

Start by reproducing the clone flow using the pipeline and organization URLs in the issue, then inspect the documentation source for references to the clone parameter. Done means the documented behavior and the observed pre-population behavior agree, with the relevant documentation updated or the implementation gap clearly identified.
