Preloading of nested lazy modules does not work #49558
Description
Which @angular/* package(s) are the source of the bug?
router
Is this a regression?
No
Description
Preload only works for siblings, not children.
For example, there is a structure:
graph LR
pages --> b
pages --> c
b --> b-review
b --> b-detail
b-detail --> b-maintenance
b-detail --> b-additional
If you go to /pages/c you'll get only b preloaded. But you could have a link on /pages/c to pages/b/detail/1/maintenance. Therefore, I want to get b-index, b-detail-index, b-detail-component, and b-maintenance preloaded.
