previous mail gets sent again when previous mail has same subject as current mail

[Bastrabun]

Repro:

Player1 sends mail with topicA and textA to Player2
Player2 sends mail with topicA and textB to Player2

Wrong: Player2 receives topicA and textA in the first mail, and then topicA and textA in the second mail
Expected: Player2 receives topicA and textA in the first mail, and then topicA and textB in the second mail

for my reference 5504

I'm not occurring this issue, maybe this is because of the order of the filters ? Note that Date - Ascending shows latest messages at the end.

EDIT: what's your version ?
