Description Jorj 2023-05-11 10:36:11 UTC 
Starting with version 1.22.0, large inter-text distances within a line seem to be ignored andno longer filled with space - linebreaks.
Command "mutool draw -o 2.txt 2.pdf" with the attached test PDF produces this output in v1.21.0:

But this output in version 1.22.0:

    Bug 706718: Don't prepend text extracted lines if vertically shifted.

    The bugfix for 706426 was incorrect, in that it did not check for
    text extracted lines being vertically shifted when considering them
    for prepending.

    Fixed here.

Thanks!
