Unfortunately a few developers are morons who misuse features, and browser vendors try hard to work around them. Case in point, lots of websites used to put `autocomplete="off"` on password boxes, which breaks some password managers. IIRC that’s why Chrome (and other browsers) decided to sometimes ignore the `autocomplete` attribute in the first place. Of course that doesn’t justify ignoring it completely (just for password fields) but maybe a similar reason is at play.
