Deleted Message Blinks but Doesn't Disappear

[Melmox]

When creating a new chat, sending a message, and then deleting it, the message briefly blinks but does not disappear from the UI. This seems to be caused by the observe closure, where liveCollection initially returns all deleted messages but then returns undeleted message.

To make this issue easier to catch, I set the debouncer delay to zero, so the UI updates instantly with every change.

Steps to Reproduce

• Open the app and create a new chat.
• Send a message.
• Delete the message.
• Observe that the message blinks.

Expected Behavior
The deleted message should disappear smoothly without blinking.
