Bug description

Standard conversation between two users (let's call them party A and party B). Party A shares a gif (from built in gif search). Party B receives the gif, but also some other images, which appear to be from another user (party A has searched their phone and does not remember the images in question). Best case the images are from another contact of B and messages got crossed, worst case they are from an unknown party, who's data has now been leaked. Luckily in this case they were not sensitive.

Steps to reproduce

• Steps as above
• I really have no idea how to reproduce

Actual result: Images which were not sent by party A appear in party B's conversation
Expected result: Images from different conversations/users shouldn't leak

I'm still awaiting device info and debug logs from Party B, I'll update when I have them. EDIT: now complete.
