When multiple windows are open, the browser sound effects of Incognito windows will stack.
Steps to reproduce:
- Ensure that browser sound effects are enabled.
- Open two or more windows, with at least one of those being an incognito window (open more incognito windows to amplify effect).
- Type, open/close tabs, or do anything else that would trigger the browser sound effects.
You should hear a sort of "doubling" effect from the sound effects.
