AVIF doesn't respect max cache size

Windows OS version

Windows 11 23H2 Build 22631.6199

ImageGlass version

9.6.0.801

ImageGlass release

Classic

1️⃣ Steps to reproduce

1: set maximum file size to be cached to 20MB and number of images to cache to 1.
2: place a small image (7MB PNG) and a large animated avif (70MB in my case) in a folder beside each other.
2: load the small image next to an animated avif.

2️⃣ Actual behavior

it takes forever to load a little 7MB PNG because it incorrectly caches the 70MB avif beside it.

3️⃣ Expected behavior

it should ignore the avif because it's over the 20MB cache limit.

5️⃣ Additional context

I tried it with a 480MB PNG next to the file and it properly ignored it.
I got the avif from here. https://github.com/d2phap/ImageGlass/issues/2033

Start by reproducing the issue in ImageGlass Classic on Windows with the cache size set to 20MB and one cached image, using the linked 70MB animated AVIF beside the 7MB PNG. Trace the cache-size check during AVIF loading and compare it with the PNG behavior; done means the oversized AVIF is skipped and the PNG loads without the delay.
