🎯 Goal

Fix composer link preview overriding actual current link preview

📝 Summary

• Increases the debouncer to 0.4s to be more aligned with how usually requests take to complete
• Fix composer link preview overriding actual current link preview

🛠 Implementation

The proper way to do this is to cancel the previous request whenever we send a new request to enrich the url. The problem is that right now we do not have support for cancellable requests in our SDK, mostly because of tech debt issues. So right now, the best way to improve this is when we show the link preview we need to make sure that url is still the one in the composer input.

🧪 Manual Testing Notes

Link preview should not show after sending the message

1. Type a valid link in the composer
2. Very quickly after typing it, send the message
3. After the message was sent, it should not show the link preview

Valid old link preview should not override current link preview

1. Type a link in the composer
2. Very quickly type a new one
3. Only the new one should be shown

Incorrect old link preview should not override current link preview

1. Type an invalid link in the composer
2. Very quickly type a new valid one
3. Only the new one should be shown (The preview should not be dismissed)
