[iluuu1994]

This issue was already fixed in GH-21124, but some JIT paths were missing.

For reference, this bright red nightly run. https://github.com/php/php-src/actions/runs/21735475020

I assume this problem was introduced by hooked properties. Right?
You know this part better...
Just check that clearing prop_info won't disable optimizations for regular properties.

@dstogov Yes. For hooked properties, the prop_info cache slot will be filled even if the property is untyped. Regular properties that are untyped will always have an empty prop_info cache slot, so they should not be affected here.
