Important

Fixes browser_action_result messages appearing in chat by ensuring they are grouped into browser sessions in ChatRow.tsx and ChatView.tsx.

• Behavior:
  • Fixes browser_action_result messages appearing in chat by ensuring they are grouped into browser sessions in ChatRow.tsx.
  • Adds logic in ChatView.tsx to handle browser_action_result and browser_action messages, ensuring they start a browser session if not already in one.
• Components:
  • Updates ChatRowContent in ChatRow.tsx to display a warning if browser_action_result is not grouped.
  • Modifies ChatViewComponent in ChatView.tsx to handle browser session grouping logic for browser_action_result and browser_action messages.

JSON.parse is used here on lastBrowserAction.text without error handling. To avoid runtime exceptions on malformed JSON, consider wrapping this call in a try/catch (or use safeJsonParse).

I noticed that when browser_action_result or browser_action messages appear outside of an existing browser session, the code creates a new empty browser session for them.

My concern is that this could lead to multiple empty or incomplete browser sessions being created if these orphaned messages appear frequently, which could impact performance and create a confusing UI with many partial browser sessions. Since ChatRow.tsx already shows a warning for ungrouped browser_action_result messages indicating it's a bug in the grouping logic, would it be better to handle these orphaned messages similarly - perhaps by skipping them or logging warnings rather than creating new sessions?
