Pictographic depiction of the problem.

SUMMARY
	Skanlite is reproducibly unable to detect scanner dimensions upon scanner reselection. It always initializes with the correct values, but never acquires them on scanner reselection.

STEPS TO REPRODUCE
	Always reproducible.
	1.  Install https://kojipkgs.fedoraproject.org//packages/epson-inkjet-printer-escpr2/1.1.49/5.1lsb3.2.fc40/noarch/epson-inkjet-printer-escpr2-1.1.49-5.1lsb3.2.fc40.noarch.rpm
	2.  Install https://kojipkgs.fedoraproject.org//packages/skanlite/24.02.0/1.fc40/x86_64/skanlite-24.02.0-1.fc40.x86_64.rpm with

OBSERVED RESULT
	I am unable to choose a preset size, and the individual value slider-inputs are all set to 0. The attached PNG file depicts this.

EXPECTED RESULT
	It should act the same as when it was first initialized.
