I'm having some trouble with TCP reassembly. Even with the "Reassemble out-of-order segments" option checked, it seems like Wireshark is not able to reassemble a TLS stream after a "Previous segment not captured" and "Retransmission" event. In this case, no packet is dropped, there are just four packets out of order.

Note how the selected packet specifies "Next Sequence Number: 1156692", which appear two packets down. But Wireshark (incorrectly?) labels it as a retransmission and loses ability to follow the HTTP2 stream.
Please let me know if a capture would be of help, I may be able to share it privately or produce one without sensitive data.
