TYPO3 Core

When building the paramaters for the preview url a condition checking the if a original version record is available seems to have syntactical issue.

in "typo3/sysext/backend/Classes/Controller/EditDocumentController.php:1032" the null coalesce operator seems to be a problem here. When having "versioningWS" true in your TCA the condition will be fullfilled even if "$recordArray['t3ver_oid'] > 0" is definetely false.

The only way fixing this would be to cut out the null coalesce assignment into a variable, then the if condition will work properly.
