I have two copies of the same site, with the same source code, where this error shows up in IE7 on one of them. This is with socket.io 0.8.7 (and now.js 0.7.6).

The line in question is:

document.body.appendChild(form);

Obviously, this code runs too early due to some weird timing issue I can't figure out. Why could this happen?

fix: catch errors when destroying invalid upgrades (#658)
425e833 
Before this change, receiving an HTTP2 upgrade would make the server
crash:

> Error: read ECONNRESET
>    at TCP.onStreamRead (node:internal/stream_base_commons:217:20) {
>  errno: -104,
>  code: 'ECONNRESET',
>  syscall: 'read'
> }

This can be reproduced with Node.js v14.15.3, v16.18.1 and v18.12.1.
