menu block or view that shows only siblings and parents It seems like this function was removed in drupal 8 so I am trying to find a solution that doesn't involve created a large amount of blocks or hard coding something. (Best would be a block or a view)

I have menu structure like this:

Parent 1
- Child 1.1
-- Grandchild 1.1.1
-- Grandchild 1.1.2
- Child 1.2
-- Grandchild 1.2.1
-- Grandchild 1.2.2
Parent 2
- Child 2.2
-- Grandchild 2.2.1
-- Grandchild 2.2.2


When I am on Grandchild 1.1.1 I want to see only the entire tree of Parent 1 (that means parent 1 plus all of its child and grandchild items), nothing from Parent 2 and below.
It seems this question has an ongoing patch at https://www.drupal.org/node/2811337 (which i found just after offering the bounty! :)
