Testcase

Spec says:

If there are no referenced nodes (e.g., for ‘feImage’ or ‘feTurbulence’), or one or more of the referenced nodes is a standard input (one of SourceGraphic, SourceAlpha, BackgroundImage, BackgroundAlpha, FillPaint or StrokePaint), or for ‘feTile’ (which is special because its principal function is to replicate the referenced node in X and Y and thereby produce a usually larger result), the default subregion is 0%,0%,100%,100%, where as a special-case the percentages are relative to the dimensions of the filter region, thus making the the default filter primitive subregion equal to the filter region.

but we ignore the "one or more of the referenced nodes is a standard input".
