simple-scan improperly sets scanned image size

[MR Zenwiz]

This is a follow-on to bug 1916550, which expired with no action taken, despite my supplying you with all the information you requested.

$ lsb_release -rd
Description: Ubuntu 21.10
Release: 21.10

$ apt-cache policy simple-scan
simple-scan:
  Installed: 40.5-1
  Candidate: 40.5-1
  Version table:
 *** 40.5-1 500

I have attached a debug log generated from the scans, and I will also be attaching the relevant screenshots, one at a time n the next 6 comments.

What I expected to happen is simply this:

When I set the Preference for page-size to Automatic, I expect the pages to scan as platen-sized for platen scans and legal sized for feeder scans. When I set the Preference for page-size to Letter, I expect to get all letter sized scans with no excess junk in the image.

Here is what happens:

Start simple-scan.
Set Prefereneces to page size: Automatic (attachment #1)
Scan an image on the platen, then scan a text, also on the platen (attachment #2)
- Note that both images are the correct size - letter+minimal extra (A4?)
Scan a text via the feeder, then scan an image through the feeder (attachment #3)
- Note that the scans are both the same size - letter+
Set Preferences to page size Letter (attachment #4)
Scan an image page on the platen, then scan an image on the platen (attachment #5)
- Note that the image scan is correctly coming out as a letter-sized page, but the text has a black box filling in a legal size page under the actual letter size paper.
Scan a text page through the feeder, then an image page through the feeder (attachment #6)
- Note these are both the correct letter size.

The command line I used to get this log was: $ simple-scan -d &> scan.log
Log attached here.

Please fix this.

I will note that one of the issues I wrote bug 1916550 has been solved, but offhand I don't remember which.

This bug still occurs in Xubuntu 22.04.1, Simple Scan version 42.1.

Now when the paper size is set to automatic, a letter-sized sheet scanned from the platen results in black filler to legal size at the bottom of the scan.

Is this bug ever going to be addressed or even checked for confirmation, or is it too low a priority at this time? Just asking, not accusing or demanding.

If you need more information, feel free to let me know.
