Under Opera 28 for Windows double clicking in the top left corner of Maximized Opera does not close down Opera like it should.

This has been standard Windows behavior for over a decade. It has worked fine in older versions of Opera such as Opera 12, but no longer works in Opera 28.

When the top left corner of a Windows application is double clicked that application is supposed to Close. Opera 28 does not implement this standard behaviour.

To recreate. Maximize Opera, then double click in the upper left hand corner. Notice it does not close Opera.

Expected Behaviour = Double clicking in the top left corner of Opera should shut it down.
