TYPO3 Core

When setting an invalid dependency in Configuration/Sets/MySite/config.yaml like

name: my-vendor/my-site
label: MySite

dependencies:
  - some-vendor/unknown

the TypoScript provided by Configuration/Sets/MySite/setup.typoscript is not available at all (resulting in No page configured for type=0.).

My expectation would be: a dependency, which cannot be loaded, would not influence the rest of the configuration.

An error is logged, so when looking into the logfile, one can grasp the problem.
