Device: Win 10.0.19045-SP0
Viewer layout doesn't scale on maximize/fullscreen since 9.10.0 update

Environment:

OS: Windows 10.0.19045-SP0
Calibre version: 9.10.0 (Bug introduced in this version, worked fine in 9.9.0)

Description:

I just updated and I am experiencing the same issue. I did not see this behavior in version 9.9.0.While the viewer now launches much faster than before, maximizing the window or entering full-screen mode does not resize the text area. The window expands, but the text content stays constrained to its original size.

Additional details about my setup:

The only setting I have customized is changing the font size to 18px.
I am using multiple highlight selections in the book (including a custom style).

Temporary workarounds:

The text only stretches to fill the full width of the window if I:
  1. Reload the book.
  2. Toggle page layout settings (switching between paged and flow mode).
