      What is requested is that in org.nuxeo.ecm.webengine.app.WebEngineFilter.initTx , instead of checking isTransactionActive, which checks only the status ACTIVE of the transaction, the call to isTransactionActiveOrMarkedRollback is made, to ckeck the fact that the transaction status can be either ACTIVE or MARKED_ROLLBACK.

      Exact code path might depend on Nuxeo version. Above stacks in Nuxeo 8.10
