Sorry, forgot to respond. I'm busy this week. Tests are added and green, so we are not far from merging. |

Suggestion for comment. Not sure I got it right, take what makes sense to you:
// Backtracking is needed when a dead end (leaf node) is reached in the router tree.
// To backtrack the current node will be changed to the parent node and the next kind for the
// router logic will be returned based on fromKind or kind of the dead end node (static > param > any).
// For example if there is no static node match we should check parent next sibling by kind (param).
// Backtracking itself does not check if there is a next sibling, this is done by the router logic.

Same here.
// Next node type by priority
// NOTE: With the current implementation we never backtrack from an `any` route, so `previous.kind` is
// always `static` or `any`
// If this is changed then for any route next kind would be `static` and this statement should be changed
Creating new PR for #1770 as @stffabi seems to be currently missing in action and I can not push to (edit) his PR ('was rejected by remote').
I would like to add PR after this is merged with:
