Offline mode renders parameters wrongly

We are developing an application with offline mode but currently encounter a problem that values in Offline\OfflineListRecords are erndered correctly but only if they are visible. Meaning if we put List.REST_test.test.testvalue in expression it is rendered properly, but if we put it as an attribute of container then all item in list get same {REST_test.testvalue} value.
Is it a bug or we are missing something?
Thank you.

Hi Mykola,

You should probably post this as a discussion about the OfflineApps component, so that the component's team gets notified of your question.

That being said, I believe the OfflineApps component doesn't support variables in custom attributes.
