What steps will reproduce the bug?

`
const _TE = new TextEncoder();
var s = "aÿ我𝑒"
var u8a = new Uint8Array(2429682061);
var offset = 38928786 ;
_TE.encodeInto(s,u8a.subarray(offset)) // { read: 0, written: 0 } failed
_TE.encodeInto(s,u8a.subarray(offset,offset+10)) //{ read: 5, written: 10 } success

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

alaways in 22.4.1

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

same as 24.14.0

What do you see instead?

const _TE = new TextEncoder();
var s = "aÿ我𝑒"
var u8a = new Uint8Array(2429682061);
var offset = 38928786 ;
_TE.encodeInto(s,u8a.subarray(offset)) // 【{ read: 0, written: 0 } failed】
_TE.encodeInto(s,u8a.subarray(offset,offset+10)) //{ read: 5, written: 10 } success
