Document background color choice is ignored

[BlebNevus]

Interestingly, this problem started a few days ago, with the previous version, and it continues after LibreOffice automatically updated today to v. 25.2.4.3, which I'm using on a Windows 10 laptop -- even though the menu for selecting this feature has been changed.

Under Tools-->Options-->LibreOffice-->Appearance-->Customizations, I've chosen my preferred color for document backgrounds (dark blue - #000099) and clicked Apply or OK. When I exit from the menu and then return, my preference is retained. But it's not working; any document I open -- a new one or an existing one -- has a white background. Why?

Crosspost on AskLibreOffice.

No definitive answers there, though, so I'd be grateful for any suggestions from people on this forum.

No problem, but it's a matter of politeness to say it's a cross post.
