Bug 489551

SUMMARY
I’m using okular v 23.08.4 as flatpak version.
I noticed that by default the print option “file → print → options →  pdf options → scale mode”) is set to 
“fit to printable area”.
This is causing that the print will be “squeezed” and not at the full size of the (letter) page.
Even when I’m changing this setting, the next time I’m opening Okular again it has the 
‘old’ value.

This is very annoying and every time when forgetting to change this setting, I’m wasting sheets of paper.

It would be nice that Okular either 
a) “remembers’ my last settings, or
b) an option is being added to the “Okular’ settings so that I can change it as needed.

Thanks in advance

STEPS TO REPRODUCE
1.  Open the option "file → print → options –> pdf options –> scale mode”.
2. Change the option from "fit to printable area" to "fit to full page"
3. Print a document
4. Close Okular and reopen it again
5. Check the settings of "Scale mode". It will be reverted to the unwanted option "fit to printable area"

OBSERVED RESULT
Okular will revert the option to the initial settings of "fir to printable area"

EXPECTED RESULT
Okular will remember my changed option at the last settings.

ADDITIONAL INFORMATION
I tried to find a config that may hold this option so that I can change it according to my need. But I couldn't find any config file that holds this option on my system.
