In this table, columns 2,3, and 4 have a static width of '1cm' and cannot be widened.
The col-spanning PGU in cell G requires more space, than these three columns provide (3 * '1cm' + table cell indentations < minIPD of G).
With no columns to expand, the content of column G overflows into cell H.

Expected warning1: 'No columns to resize to fit a table-cell spanning these columns, expect overflows'
Expected warning2: 'The contents of fo:block line 1 exceed the available area in the inline-progression direction by 5318 millipoints. (See position 56:26)'
