Microsoft Edge of late has begun repeatedly showing me this pop-up dialog almost every time I try to close its window after a browsing session (cannot predict or figure out what causes it not to show up sometimes):
How do I block it for good without pinning those sites? (Assuming it'll stop bugging me if I do, which is not guaranteed.) I haven't found any Experimental Flags related to this 'feature' yet.
Edge is updated to the latest Version 115.0.1901.188 (Official build) (64-bit), running on Windows 10 x64 22H2 (build 19045.3208).
