	- name: Skip if pull request is in Draft
	# `if: github.event.pull_request.draft == true` should be kept here, at
	# the step level, rather than at the job level. The latter is not
	# recommended because when the PR is moved from "Draft" to "Ready to
	# review" the workflow will immediately be passing (since it was skipped),
	# even though it hasn't actually ran, since it takes a few seconds for
	# the workflow to start. This is also disclosed in:
	# https://github.community/t/dont-run-actions-on-draft-pull-requests/16817/17
	# That scenario would open an opportunity for the check to be bypassed:
	# 1. Get your PR approved
	# 2. Move it to Draft
	# 3. Push whatever commits you want
	# 4. Move it to "Ready for review"; now the workflow is passing (it was
	# skipped) and "Check reviews" is also passing (it won't be updated
	# until the workflow is finished)
