Mouse wheel over transcript navigates prompt history instead of scrolling, when input is focused

Environment: Claude Code desktop app, Windows 10

Description:
When I open a chat, the input box has focus by default. Scrolling the mouse wheel — even while the pointer is over the chat transcript area — navigates through the input/prompt history (previous/next submitted messages) instead of scrolling the transcript. The wheel only scrolls the transcript after I explicitly click on the chat/transcript area, which is awkward. My first action on entering a chat is usually to scroll up to read the model''s response, and it jumps through the history instead.

Expected behavior:
Scrolling the wheel while the pointer is over the transcript should scroll the transcript regardless of input focus — or provide a setting/keybinding to disable "wheel → history navigation".

Workarounds tried (did not help):

• Unbinding up/down in the Chat context via keybindings.json — no effect (the behavior is not routed through those bindings).
• Binding wheelup/wheeldown → scroll:lineUp/scroll:lineDown in the Chat context — no effect.
