Array buffer allocation failed exception

[Akito0723]

I am trying to preview a PDF file over 2GB in Chrome 131.0.6778.205 using PDF.js(v4.5.136). Even though I am using chunked loading, I still get an Array buffer allocation failed exception.
For PDF files smaller than 2GB, this exception does not occur, and I also confirmed in the network that there are response with code 206.
After debugging, I found that in the src/core/chunked_stream.js constructor, a new Uint8Array(length) is used, where length corresponds to the size of my PDF file, 2456564609. I modified it to new ArrayBuffer(length, { maxByteLength: length }) and it worked. I want to know if this is by design or due to some other reason.
