Latest Chrome stable on Android 9, but it has happened on my previous phone as well (Chrome stable, Android 7.1). Likely happens on Chrome and Firefox on Windows 10 too but I browse much more on my phone.
EDIT: I have no notifications now (of course) but if I get at least two/three (I'm sure it happens with the latter, haven't tested for the former) or you can generate them I can send those screenshots.
