Bugzilla #44621: when the after border of a cell, in the trailing case, is bigger than in the normal case, the generated sequence of Knuth elements was wrong, leading to content being swallowed
This is a partial fix only: the content is no longer swallowed, but the penalty is wrong (shorter than it should be). This will lead to the table overflowing the region-body without warning.
