reconnect fail on Firefox

[d2school]

I write the sample-project "chat" with " options { reconnect: 5000 }". After I restart websocket server, ws-clients in Edge or Chrome are working fine and successfully reconnecting, except for Firefox.

OS: Ubuntu 22.04, Firefox: 116.0.2

I found the reason:
file: /src/neffos.ts
line : 925

-if (isNull(resolve) || resolve.toString() == "function () { [native code] }") {
+if (isNull(resolve) || resolve.toString() == "function () { [native code] } || resolve.toString() == "function () {\n    [native code]\n}") {

since the result of "resolve.toString()" in Firefox is

function () {
    [native code]
}

(there are 4 spaces before "[native")
but not:
function () { [native code] }
