This problem is caused by using shared sample objects without properly clear the old crypto info of previous inputs. A regression of bug 1308405.

The patch landed in nightly and beta is affected.
:jhlin, is this bug important enough to require an uplift?
If not please set status_beta to wontfix.

No issue encountered while testing this issue on Android (geckoview-example app), following the steps from the description with Samsung Galaxy Note 10 (Android 10) and Nokia 6 (Android 7.1.1). The FxR issue is also verified and I will update this one as well.
