This form was missing autocomplete:
I added autocomplete to the form, as well did I add the attribute name=“email” to the input-element to make sure autocomplete will work as hoped for. A prewritten FORM-mod might have autocomplete already prewritten inside of it to ease the developers workload.
This is a nice addition to the forms, thank you for suggesting it! We are also working on features that will enable you to contribute to community modules directly; so you’ll be able to make a change like this and recommend that it gets merged, and then others will be able to see that you helped out. Looking forward to that, but in the meantime thank you!
