Improve interaction between search and assistant

[Blargian]

The search dialog conveniently populates the prompt "Ask AI about ..." before your search term:

However, when you click this button, it pre-fills only the search term by itself in the Assistant chat:

The assistant often gives a response that it doesn't know what you are asking.

Expected behaviour: When clicking "Ask AI about X search term", the prompt which is added to the assistant should be something like "Tell me about X search term" for better results.
