Target type `tool` does not list bundle dependency in Dependencies Build Phase

It does appear in the Copy Bundle Resources Build Phase, but not in the Dependencies Build Phase. This results in the bundle not appearing at runtime. If I manually add the bundle target to the tool target's Dependencies Build Phase in the Xcode GUI, the tool runs successfully and can find the bundle contents.

relevant spec portion:

targets:
  createYear:
    type: tool
    sources: [createYear]
    platform: macOS
    deploymentTarget: 10.15
    dependencies:
      - bundle: copyYearResources
  createYearResources:
    type: bundle
    sources: [createYearResources]
    platform: macOS
    deploymentTarget: 10.15

result:

expected, which works for my tool at runtime:

Start from the target and dependency handling represented by the provided YAML specification, then compare the generated Xcode Build Phases for the tool and bundle targets. Use the expected Xcode GUI configuration as the reference; done means the bundle dependency appears in the tool target's Dependencies Build Phase and the tool can find the bundle contents at runtime.
