Rework the way params are assigned to TaskIncludes when they're dynamic

Browse source 
Copying the TaskInclude task (which is the parent) before loading the blocks
makes the code much more simple and clean, and fixes a bug introduced during
the performance improvement changes (and specifically the change which moved
things to a single-parent model).

Fixes #17064
