<![CDATA[System theme sync stops working starting from Opera 126.]]>Environment:
macOS 15.7.4
Apple Silicon M5 MacBook Pro

Opera 125 – system theme sync works correctly
Opera 126+ – "Follow system" no longer responds to macOS light/dark changes

Steps to reproduce:

  1. Set Opera theme to "Follow system"
  2. Change macOS appearance between Light and Dark
  3. Opera does not update

Reinstalling Opera and resetting the profile does not fix the issue.

Works in 125
Broken in 126
