The Line 3 and 4 are grouped into the nested blockquote, not the outer blockquote. This should generate a BLOCKQUOTE with a PARAGRAPH, a BLOCKQUOTE (with a PARAGRAPH containing just Line 2), and a second PARAGRAPH. But instead the BLOCKQUOTE is generated as a PARAGRAPH and a BLOCKQUOTE with a PARAGRAPH containing Lines 2-4.
This example fails:
