Changelog Entry

Description

This PR enhances the LLM's context awareness in channel chats by injecting current emoji reactions and ensuring quoted/replied messages are always included in the history. It also fixes a RangeError in RichTextInput.svelte.

Key Changes:

Reaction Context: The LLM now receives [CURRENT REACTIONS: ...] tags for messages, allowing it to "see" and respond to user reactions (e.g., upvotes, custom emojis). A system prompt update instructs the model to prioritize these tags over text content.
Thread Continuity: Guaranteed inclusion of the thread's root message and any directly quoted/replied messages in the context sent to the LLM, fixing issues where the model lacked context for specific replies.
Bug Fix: Resolved a RangeError in RichTextInput.svelte caused by accessing depth on a root node.

Added

Logic to fetch and format emoji reactions into the LLM context string.
System prompt instruction to handle [CURRENT REACTIONS: ...] tags.
Logic to trace and include parent_id (thread root) and reply_to_id (quoted message) in the thread_messages list.

Changed

Updated model_response_handler in backend/open_webui/routers/channels.py to process reactions and manage message history more robustly.

Fixed

RichTextInput.svelte: Added a check if ($from.depth === 0) return false; to prevent errors when querying node depth.
Fixed missing context for LLMs when replying to messages that fell out of the immediate history window.

Additional Information

This addresses the need for the LLM to understand social cues (reactions) and follow complex thread structures more accurately.
If this PR were merged, it would fulfill and satisfy the feature request I've submitted in the Open WebUI Discord server on October 12, 2025.
