Just code to help replicate issue with Internet explorer
Trying to create minimal app with specific issue on Internet Explorer 11/10.
It happens when some submodule returns Html.text "" and it's mapped to specific Msg in parent module.
When this submodule state is changed and Html.text "" is replaced by some other stuff with Events, those Events are not propagated
to parent module. In source code of Elm is missing info about mapped Msg.
Dumped code via debugger from real live code:
Chrome vs IE (simple dump of objects - patches from compiled Elm code)
20 397 p-redraw #text undefined undefined undefined NaN|undefined|tagger: function (a) {
return {ctor: 'UpsellMsg', _0: a};
}| undefined|parent|undefined||tagger: function enqueue(msg)
{
_elm_lang$core$Native_Scheduler.rawSend(mainProcess, msg);
}| undefined||parent: undefined|
20 397 p-redraw #text undefined undefined undefined undefined
Open IE (11,10) ideally with cleared browser cache. Open URL below or local host project make dev
and try to click on "Open", you'll see another button but clicking on this second button doesn't work.
Event not attached via Elm (onClick attribute) is fired (see console) but Elm msg is not properly handled.
For now it's not working only on first load of page (without cache) but we had this issue on our project (on production) and this bug was caused every time (even if you reload page).

Video with bug recorded here: elm-ie-bug.mov Recorded on IE version 11.0.9600.18860 see EI-version.png
I hope this is enough to reproduce this bug on every device with Internet Explorer.
