1.43.3 - completely broken display

[m3w88]

This wiki was recently forked from Fandom to mediawiki 1.43.3 on php 8.1. Upon installing PortableInfobox, performing page purge and null edit no longer restores expected display of the templates.

I understand that Miraheze upgraded to 1.43.1 and Fandom is still on 1.43.1.
I have been informed reaching out to the WMF parsoid team with no guarantee of a fix.

PortableInfobox has been tested to work on both 1.43.3 and 1.44 and it appears to function properly for me. What commit of PortableInfobox are you using?

PortableInfobox currently appears to work on the example page linked above. Special:Version is disabled, but the page source still reports the version as 1.43.3.

At the time of filing, the latest commit via a git clone.
It would appear that fandom made changes that are unsupported or out of sync. Copying templates to miraheze beta wiki returned no issues.
Difficult to identify why its broken for forked wikis vs built from scratch templates

Apologies for late response, as fandom runs on 1.43 that is the version in usage. Special:version is hidden for operational security purposes.
