Discuss how to fix extending an internal Drupal core base class

Thanks @Grevil I agree we should suggest to make the base class non-internal in core. It's very helpful and would be better to not have it market @internal.

Until that's solved I hope there are no issues with this method besides the warning.

Postponed on ✨ Make MultiWidthLayoutBase non-internal Active

The core issue is now fixed, so that we should be able to solve this here and in drowl_layouts_bs?

Nothing to solve here! "DrowlLayoutsMultiWidthLayoutBase" still extends "MultiWidthLayoutBase", but since "MultiWidthLayoutBase" isn't internal anymore, we now do not get a warning anymore! :)

Fixed through ✨ Make MultiWidthLayoutBase non-internal Active !
