Comment (by peterwilsoncc):

 @jrf and I had an in person discussion about this last night.

 * the cause of this ticket is that the cron array includes items in stored
 in an unexpected format
 * unexpected data in the cron array was also causing a problem in PHP 8.1,
 fixed in [51695]
 * each of the cron functions assumes `_get_cron_array()` returns a
 correctly formed cron array. This isn't entirely a safe assumption as a
 plugin may save it incorrectly or filter the `cron` option getter.

 As PHP becomes stricter about type and introduces more fatal errors for
 incorrect type issues, we were considering whether it would be better to
 validate the cron array on the way out.
