+Subject: fix: disable implies dcheck for node stream array buffers
+
+Added in this CL: https://chromium-review.googlesource.com/c/v8/v8/+/3035091
+
+This commit was added in preparation for ResizableArrayBuffers
+and GrowableSharedArrayBuffer. If a buffer is not resizable and
+has a larger max_byte_length than byte_length, we throw.
+
+However, the check also catches on Node stream buffers, which
+on readStream will slowly fill their byte length up to the
+maximum length. Streams do not yet have the resizable
+property.
+
+This patch can be removed when streams support rab/gsab, or
+when support is synchronized across both v8 and node.
