Modal popups for users and instances don't always show correct user/instance

[jheretic]

Occasionally, when you click on a user or instance it shows the information from a different user or instance.

Hi! I'd like to take this on. It sounds like a state synchronization issue where the modal doesn't reset when switching between users/instances. I'll investigate the frontend components and propose a fix. Let me know if there are any specific constraints!
