Unable to add more than one filter in autocomplete view

When editing the supplied view (at /admin/structure/views/view/nodes_autocomplete) and adding a second filter, exposed or not, it would just be ignored when trying out the search suggestions.

All my filters were connected by "AND". I tried adding a "Content: Type (=Article)" and a "Content: Published (=Yes)" filter, for example. Also, when trying to ad a contextual filter with a default value to the nodes_autocomplete view was also ignored, even though it is reported to work here → .

In all these cases, the additional filters would have their desired effects on the view preview page (e.g. http://www.example.com/en/admin/structure/views/nojs/preview/nodes_autocomplete/page?title=test), but they would have no effect when using the real URL (e.g. http://www.example.com/de/nodes-autocomplete?title=test).

Workaround: When recreating the same JSON output with View Datasource → (module views_json) as suggested here → , there were no issues and adding a second, third etc. filter went flawlessly.
