Scroll Behavior in R3

[jakobrosenberg]

Glossary

• standalone nodes <slot /> - a single node is rendered in the slot.
• inlined nodes <slot inlined /> - all child nodes are rendered in the slot.

Expectations

If a #hash anchor is present in the URL

• The corresponding element should recursively be scrolled into view of all its ancestor elements. Parent, grandparent etc.

Else:

• When new a new standalone node is rendered, it should be scrolled to the top of its parent node.
• When new a new inline node is rendered, it should recursively be scrolled into view of all its ancestor elements until it reaches its boundary element. The boundary element is normally the parent node, but can also be set to an element further upstream (eg. on the html document, if we want to treat the node as a #hash anchor).

Note 1: This is just a preliminary draft. I'll update it based on input.
Note 2: Inlined nodes are currently enabled with <slot multi />, but will be refactored to <slot inline />.
