[Bug] No gap between images and landscape image is too large

[imammansyur]

Device information

• Suwayomi-Server version: v0.7.0-r1479, WebUI r1361
• Server Operating System: Windows 10 22H2 Build 19045.3996
• Server Desktop Environment: N/A
• Server JVM version: bundled with windows-x64
• Client Operating System: Windows 10
• Client Web Browser: Google Chrome 121.0.6167.86

Steps to reproduce

1. Open any chapter
2. Set the "Reader type" to "Continuous vertical"
   
3. Turn on "Fit page to window"
   

Expected behavior

When "Fit page to window" is turned on, there should be a gap between images as shown when "Fit page to window" is turned off.

Actual behavior

There's no gap between images. And because it fits on vertical axis, landscape image is too large on horizontal axis.

Other details

This problem also happened on WebUI r1335. Haven't tried on another "Reader type" other than "Continuous vertical."
