Hello,

Concerning the above it is answered in large part in the MSDN article
"Object Lifetime Events"

I quote from this articel below:

the Loaded event is raised as a coordinated effort throughout the
entire element tree (specifically, the logical tree). When all
elements in the tree are in a state where they are considered loaded,
the Loaded event is first raised on the root element. The Loaded event
is then raised successively on each child element.

Note:
This behavior might superficially resemble bubbling for a routed
event. However, no information is carried from event to event. Each
element always has the opportunity to handle its Loaded event, and
marking the event data as handled has no effect beyond that element.
