At certain moments, I enter a wrong alias because the browser displays previous entered values for these input fields. The chance that a user needs to add the exact same alias to a lot of items is very small (correct me if I'm wrong). Should this be disabled (and how, I've read that there were some browser changes around this subject)?
It mostly happens when I want to add a alias that is similar to a previous entered value (imaging adding "Wikidata" as a alias, with "Wikidata Query Service" as a previous entered value in the past). If I don't pay attention, it would select "Wikidata Query Service" if I type "Wikidata" (at least in my browser, Safari), because it will autoselect that suggestion. Hope this is clear enough.
This doesn't seem to happen for me.
Although it doesn't look like the first has auto complete turned off
