Description Fujii Hironori 2022-05-30 15:00:06 PDT

REGRESSION(245163@main) Can't load a very large image as an image document

1. Download a very large image (>100MB) from somewhere
   For example, https://esahubble.org/images/heic1901a/
2. Load the image directly

Actual: Can't finish loading
Expected: Finish loading the image

combineSegmentsData of SharedBuffer.cpp is being called very frequently every time new data received.
On the other hand, before 245163@main, thank for CachedImage::shouldDeferUpdateImageData, it is not called so frequently.
