Commented lines of code changing eel behavior (actually)

[panthuncia]

Eel version
0.16.0
Describe the bug
Commented lines of code changes how Eel executes under very specific circumstances involving functions generated at runtime. These functions seem to require two eel.expose calls to be exposed properly, but only the first needs to execute. The second can be commented.

I'm not sure if the code I'm writing should work or not, but it definitely shouldn't do this.

To Reproduce
Steps to reproduce the behavior:

create a div like this:

<div class="div_class" id="SomeDiv">
    <p>SomeDiv</p>
</div>

and as many more of that class as you would like

Define functions in a loop like this:

for (const div of document.getElementsByClassName("div_class")){
    funcName = div.id+"Func"
    window[funcName] = () => {
        console.log("In function")
    }
    eel.expose(window[funcName], funcName)
}
//eel.expose(SomeDivFunc)

and call the function from Python.
This should work (it does for me).

Now, remove the commented line.

for (const div of document.getElementsByClassName("div_class")){
    funcName = div.id+"Func"
    window[funcName] = () => {
        console.log("In function")
    }
    eel.expose(window[funcName], funcName)
}

Now, eel fails to load the function, and we get "module 'eel' has no attribute '<name>'".

Now, if we uncomment that line, and comment or remove the first eel.expose:

for (const div of document.getElementsByClassName("div_class")){
    funcName = div.id+"Func"
    window[funcName] = () => {
        console.log("In function")
    }
    //eel.expose(window[funcName], funcName)
}
eel.expose(SomeDivFunc)

The app will execute, and the python call will not generate an error, but the function will not be executed.

Expected behavior
The commented line should have no impact on code execution, as it is commented.

Additionally, it is strange that this functionality requires both of these eel.expose calls for the function to be exposed successfully. Neither expose alone works, but the second one can be commented and it will still work.

Is this even supposed to work? It is a somewhat strange use-case.
