bug#33634: Strange behavior from gparted

[Brent W. Baccala]

Hi -

I just using gparted 0.32.0 on Ubuntu Bionic 18.04 to move and resize a partition.

Initially, there was a 25 GB partition and a 100 GB partition followed by a 574 GB partition.  The operation was to remove the 25 GB and 100 GB partitions, move the 574 GB partition backwards to align with the old partition's start, and resize the new partition to approx 698 GB.

Take a look at the attached gparted_details.htm.  It looks like after the old partitions were deleted, the 574 GB partition was moved and resized to 698 GB in one step, then resized back to 574 GB, then resized again to 698 GB.

Everything worked out fine, but this looked to me like some kind of bug, so I thought it was best to report it.
