OpenMage+php7.4 - "Serve cached pages to crawlers on initial visit" not working

[m-overlund]

After upgrading from Magento 1.9.4.5 > OpenMage LTS 19.4.15, Turpentine started serving Googlebot HTTP 302.

When clearing the setting Caching Options > Crawler User Agents Googlebot again is served HTTP 200 as expected.
