Describe the bug
When opening large cbz files (~900MB) foliate uses too much ram. At startup it consumes all of my ram (I have 8GB of ram), the system just hangs up and after a while the ram usage stays at ~2GB (most of the memory is consumed by the webkit network process). Meanwhile evince uses ~70MB of ram for the same cbz file. Foliate also takes longer to load the file.

To Reproduce
Steps to reproduce the behavior:

1. Open a large cbz file with foliate.
2. Monitor the system using system monitor.

Expected behavior
Foliate should not use this much ram.

Version:

• Foliate version: 2.6.3
• OS/Distribution and version: Arch-LInux
• Desktop environment: Gnome 41.1
• Installation method: package from official arch repo
