[Elastic APM] transaction(xxx, xxx, custom) was discarded! The page was hidden during the transaction!

Hi,
We are trying to capture a long running custom transaction where the user might be inactive for a while, switch tabs/windows etc. We could not see these logs on kibana. so we turned on the debug log level and in such cases we can see that the transaction gets discarded with the message '[Elastic APM] transaction(xxx, xxx, custom) was discarded! The page was hidden during the transaction!'. How we can we disable this? Is there a config to control this behaviour?
We are using @elastic/apm-rum-angular: 2.0.0 and use chrome.
Thank you.

Regards,
Sibi
