Hi Deri, thanks for testing this.  I'm using groff 1.21, but what I
failed to note in my bug report (as it's the default on my system,
so I didn't think about it) is that I was using US letter papersize.
However, I just reran the test case with a papersize of A4, and I see
the same results I saw before: the first page ending with 53 using the
original source, and then the entire block being moved to the next page
using the modified source.

So apparently the default page layout has changed slightly between groff
1.21 and 1.22.2.  And if in the newer groff the first page ends with
the block, the expected result would be for the entire block to move if
another line is inserted above the block.

The question is, does 1.22.2 fix the bug?  That is, if you set up your
original file so that only one line appears after the block on the first
page, what happens when you then modify the source file to add a line
before the block?
