I don't see this as a bug. Password autocomplete is kind of a dumpster fire. It varies, depending on which sites I visit.<p>I use 1Password, with browser integrations (it works better with Safari than Chrome).<p>I don't know most of my passwords; relying on 1Password to access the strings of garbage I autogenerate.<p>So I am <i>constantly</i> using it to fill forms.<p>It keys on things like attached <label>...</label> elements. Not all sites use these. Some sites also sometimes add some kind of junk that causes 1Password to fail.<p>Other times, 1Password insists that the field I just selected needs an autofill; even for non-auth fields.<p>Not really a big deal for me. No one that shouldn't gets my auth, and I ignore the prompt when it is not necessary.
