I'd actually be more inclined to suspect that it's the Symbol
and FeatureBlock renderers which are being over-zealous about
clipping -- at a quick inspection, LayeredRenderer just seems
to preserve the same width of clip which it inherits.  Or have
you tried using SymbolSequenceRenderer both inside a LayeredRenderer
and on its own?

Go for it!
