Challenge 2: A Drop Shadow Disappearing Near a Frame's Edge — Solution Walkthrough

The answer:

Per this chapter's own warning box, a Frame clips its own contents to
its boundary by default. When the button sits close to the edge of its
parent Frame, the shadow — which visually extends slightly beyond the
button's own shape — gets cut off by that clipping boundary the moment
it crosses the Frame's edge, rather than showing as a natural overflow
the way it might on a plain artboard.

Why this is easy to miss:

The button itself still looks correct, since only the shadow (which
extends past the button's own visible bounds) is being clipped. This
makes the disappearance easy to misdiagnose as a shadow-setting problem
rather than a clipping-boundary problem, since the actual shadow
effect settings likely haven't changed at all.

What actually fixes it:

Checking the parent Frame's own clipping/overflow setting — and either
disabling clipping for this Frame or giving the button enough margin
from the Frame's edge — resolves the disappearing shadow without
needing to touch the shadow effect itself.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that unexpected content disappearing near a
Frame's edge is correctly traced back to default clipping behavior,
not a problem with the effect or element itself.
