Show all matching results once filtering starts

Problem/Motivation

Even if configured to show only ten facets, say, once somebody starts filtering they do not expect their matches to be limited to those ten. All possible results should be shown— or at least the same number of facets that are shown originally, the original list of ten should not be the only source for matching results of what is typed in the "Filter" box.

Unfortunately that is what is currently happening, if you have configured it to show only ten results, and you filter for something that has two results, and one is in the first ten but the other is after that, the filtering will show only the first match and the "Show all" button, and you need to press "Show all" to see the second match.
