At the very least, the placeholder should be translated.

The feature is to address the accessibility issue where the filter text box doesn't have an associated LABEL element or title attribute that describes its purpose nor a way to specify them, either of these would be appropriate:

1. A way to specify a title or label value for JUST the search box (and have it rendered...)
2. Automatic labeling / titling of the search box (Could be as simple and generic as "Search List")
