Interface field autocomplete no longer present in 1.0+ #1691
Description
I am looking to upgrade my very old graphiql package to the latest stable, jumping from 0.11.11 to 1.0.5. During this transition, i found that when working with interfaces when upgrading from 0.17.5 (the last stable 0.x) to 1.0+ the way interface fields are suggested changed.
Previously, when working with interfaces all interface fields would be autocomplete
With anything in the 1.0 series, all interface fields now require a fragment to be found. The only field that autocompletes is __typename. Also the interface itself is being returned as a suggested autocomplete when trying to build a fragment instead of just the concrete instances.
I couldn't find anything in the issues or the change log about a breaking change like this and wondering if this is intended or if something else is going on in the schema that was being delivered to graphiql.
