mtlcl410andClaude Opus 5.5 7e0f635856 M12: XFA table rows repeat in positioned containers ...

A table subform (layout="table") placed in positioned content was drawn
through draw_node, which drew each row subform once: the rows the data
holds past the first, and an occur initial count, were dropped with no
warning, while the same table in flowed content repeated them (XFA 3.3,
"Tables", p. 327; "Repeating Elements using Occurrence Limits", p. 263;
Chapter 9, p. 336).

The positioned table now draws each row once per instance, one under
another with its own SOM index, and is measured with them, so what
follows it in a top-to-bottom container moves down. The count and the
warning for the rows cut come from one helper, laid_out_instances, now
used by every layout that repeats a subform (flowed subforms, flowed
tables, positioned top-to-bottom, wrapped and table layouts).
