is there any workaround for <https://youtrack.jetbrains.com/issue/KT-68185|[WasmJs] Attach js exception object to JsException>? I'm still on 2.0.10 and <https://github.com/krzema12/snakeyaml-engine-kmp/pull/272#discussion_r1842177273|my tests are failing on Wasm>, but I don't know why. I just want to get to the true reason of the exception to diagnose the tests, I don't care for a proper workaround in production for this bug

Maybe increasing stack trace limit will give you additional insights

declare and call following function before failing code
```fun setStackTraceLimit() = js("Error.stackTraceLimit = Infinity")```

To get JS exception you can define
```fun &lt;T : JsAny&gt; jsCatch(
    throwException: (e: JsAny?) -&gt; Unit =
        { e -&gt; throw e?.toThrowableOrNull() ?: Exception("JS: " + e.toString()) },
    f: () -&gt; T
): T  = js("{ try { return f(); } catch (e) { throwException(e); } }")```
and wrap failing code like here:
```    fun test() = runTest {
        jsCatch {
            throwsJsException()
        }
    }```


thanks! using this technique (with a little adjustment:
```fun jsCatch(
    f: () -&gt; Unit,
): Nothing = js("{ try { return f(); } catch (e) { console.log(e); } }")```
) I found out why this test fails

it has something to do with <https://github.com/krzema12/snakeyaml-engine-kmp/blob/bd8ffe043fd0db28de598cbb21ce67af2d75ec0c/src/wasmJsMain/kotlin/it/krzeminski/snakeyaml/engine/kmp/internal/system.wasm.kt#L17|https://github.com/krzema12/snakeyaml-engine-kmp/blob/bd8ffe043fd0db28de598cbb21ce[…]tlin/it/krzeminski/snakeyaml/engine/kmp/internal/system.wasm.kt> - `WeakMap` doesn't have a `contains` method, but it does have `has`: <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WeakMap/has>. So it looks like an issue with our code, I'll investigate further, thanks!
