Ventura Window Size (preference App)

I have just updated to Ventura and want do check/set preferences. The new Preferance app/window looks nice (similar to Iphone) which probably makes it easyier to find things across Devices/OS. But when i want e.g. to set a Background i did not see all Pictures (they are ,,cut" on the right side because of the window size. So i want to change it, but i cant. The only thing i can change is hight but i can not make it larger (in width). Is this hat it should be or a bug :) Thanks for info and maybe this can be change with next Update.
