Under the hood
Chat input box internals were re-memoized with no visible feature change
What
The internal caching logic for the chat input box's React component was regenerated with new internal names and cache slot positions. The visible behavior it supports—history navigation, pasting, opening an external editor, pasting images, and toggling the workflow keyword—looks the same as before.
Why
This appears to be internal refactoring rather than a change that affects how typing or pasting in the input box works.
