When replacing the internal buffer of a SharedBuffer with mmap'ed file-backed pages, we may still have an ImageSource (inside of CachedImage::m_image) retaining the old heap-allocated resource buffer. This means that we pay double the memory cost for encoded data in downloaded resources that get cached for the first time.
