In particular, I recently ran into a very long-running issue where Chrom[ium] attempts to auto-fill inappropriate shit (like names from saved credit cards) into utterly unrelated form fields.
This has been going on for many years now [0], because maintainers insist their browser must ignore standards like autocomplete="off" [1] and use some "crowdsourced" remote-server fuzzy-recognition bullshit, and when their AI system is terribly wrong there's way for pages to opt-out.
This is especially aggravating for any developers who cannot meet WCAG accessibility guidelines that might be required of them by contract or law, and people have submitted a litany of other problematic examples [2] to no effect.
