Class: Buffer do not follow when the underlying ArrayBuffer is resized #52195

Version

v21.7.1

Platform

Microsoft Windows NT 10.0.22631.0 x64

Subsystem

Class: Buffer

What steps will reproduce the bug?

const arraybuffer = new ArrayBuffer(4, { maxByteLength: 4096 });

const uint8array = new Uint8Array(arraybuffer);

uint8array.set([0,1,2,3]);

const buffer = Buffer.from(arraybuffer);

console.error(uint8array);
console.error(buffer);

arraybuffer.resize(8);
uint8array.set([4,5,6,7],4);

uint8array[0]=0xff;

console.error(uint8array);
console.error(buffer);

Output:

Uint8Array(4) [ 0, 1, 2, 3 ]
<Buffer 00 01 02 03>
Uint8Array(8) [
  255, 1, 2, 3,
    4, 5, 6, 7
]
<Buffer ff 01 02 03>

How often does it reproduce? Is there a required condition?

always

What is the expected behavior? Why is that the expected behavior?

Expecting buffer to be resized and output to be:

<Buffer ff 01 02 03 04 05 06 07>

What do you see instead?

<Buffer ff 01 02 03>

Additional information

If the resolution to this is that Buffer isn't going to support ArrayBuffer.resize() that should be reflected in the documentation.
