fix(domain): custom domain should not filter data (#1181)

Domain bounds should be used in the sense of zooming in/out with a viewport on the chart. A regression of this behavior slipped through due to a [PR](#896) causing data to be filtered out when applying a custom domain, removing data points from areas and lines. The right behavior is now restored.

fix #1129
