This reverts commit e2a7740322.
structuredClone errors in these browsers were a symptom of inavertently
including Error objects in reporter events. In newer browsers,
structuredClone can copy those objects, but it's lossy: if an instance of
an Error subclass is cloned, the result is an instance of Error.
With that fixed, Jasmine is compatible with Safari 16 and FF 102. At least
for now. And keeping them around may provide a way to detect similar bugs.
