Final Private Method in TrialMetadataHandler.class.php incompatible with PHP8

[Time Axis]

Line 332 of TrialMetadataHandler.class.php has a “private final function”. This is redundant, as a private function wouldn’t be overridden anyway. This creates an error in a mocked install on PHP8 which hangs the editor and player on a perpetual loading screen (more details here). The solution is to change that line from private final function ensureUpdateArrayIsSet($lvl1, $lvl2) to simply private function ensureUpdateArrayIsSet($lvl1, $lvl2)
