Uninstalling a module deletes dashboards that have a block provided by that module

I'm not 100% sure if the proposed solution is the right UX.

The user has a confirmation form where it's informed that this would happen. They could always go to the dashboard, remove the offending blocks, and try to uninstall again.

I think this could use ConfigEntityInterface::onDependencyRemoval()

Good call, Probably we should do just as in \Drupal\layout_builder\Entity\LayoutBuilderEntityViewDisplay::onDependencyRemoval and remove the block or section affected.

That MR is straight copypaste from LayoutBuilderEntityViewDisplay and works as expected. This needs tests tho.

Code LGTM!

tested manually and the blocks from the uninstalled dependencies are removed, leaving the rest of the dashboard unaffected.

Marrking as RTBC.

Out of the scope this issue but I wonder if would be worth to open a core issue where these methods would be moved to a trait for scenarios like this.

Not opening a follow-up now for core, but tagging this for being able to find it later.

Thanks!
