Unable to locate "Leave site?" exit speedbump on Chrome v108

Afternoon

is anybody aware of an update to this speedbump on leaving the chrome browser?

We have a name mapped item:

and associated button:

We call this after we send a browser.Close() step in an OnStopTestCase event to catch if the .Close() fails.

Some reason this is no longer working (chrome v108) and if I try to object spy or add a new object, it is not recognised

Any ideas?!
