Could we add a comment here stating that this may return found=true even if this
is giving back a failure, I at least had to convince myself that in case of GC
during the callwould always be safe. Also, this would be nice to know for other
callsites in the future (i.e., that even when found, they should check the
result if they do not immediately return it)

could we use a more descriptive name for this?
Like, SetPropertyWithCallbackSetterInPrototypes
