pathinfo() is locale aware[1][2], so please double-check whether
the two scripts run under the same locale.

Interestingly, with the "C" locale, only PHP 8.0 produces the
expected result[3].

PHP 8.2+ (versions with active support) produce expected result so nothing to do here. Probably got fixed as some part of other fix in 8.0.
