Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=138775

I've fixed the `beforeunload` case, since it happens during `load_nsuri`. I added tests for both it and `unload`, but unfortunately the new tests are somewhat hackish, as we have to release the View without actually closing it to test this, because closing the view sends those events (this is already tested by existing tests), and we want to test if releasing the doc obj sends those events. As for why we have to release the View, it's because it holds a ref to the doc obj.
So I placed the test last now since it doesn't close the view properly. If you think the test is too hackish I can remove it.
Jacek Caban (@jacek) commented about dlls/mshtml/oleobj.c:
if(!ref) { if(This->doc_node) {
This->doc_node->doc_obj = NULL;IHTMLDOMNode_Release(&This->doc_node->node.IHTMLDOMNode_iface);
/* Protect against re-entry by grabbing it here */This->ref++;
Please avoid it. You may just fully detach document object early, before releasing and uninitializing window and document node to be sure that we don't reenter the destructor. It could also simplify handling of skipping mutation events.
To be honest I'm not thrilled with the idea of doing full load like that. I was hoping for something "lighter". Sadly, I don't see a good alternative to do that in Gecko in a way fully compatible with MSHTML. I'm not sure how much we really care about this thing being exactly compatible, but if we do, I guess we need something like that...
FWIW, one alternative would be to do `document.open(); document.close();`. It would work only on HTML documents (no SVG/XML equivalent) and it replaces a document instead of creating a new one, so it's not really a good fit.
BTW, it 's hard to judge without seeing the code, but find it surprising that this thing matters for MessageEvent.source.

To be honest I'm not thrilled with the idea of doing full load like that. I was hoping for something "lighter". Sadly, I don't see a good alternative to do that in Gecko in a way fully compatible with MSHTML. I'm not sure how much we really care about this thing being exactly compatible, but if we do, I guess we need something like that...

Yeah I tried a bunch of things and arrived to this one. I agree something lighter would be nicer, but I'm not sure if it's that bad since it happens on the document obj release (which is typically not that often, since it's the "root"), and we're already doing some other potential heavy things here, such as forcing a cycle collection. I haven't tested but this *might* also help with the gecko nsevents that hold refs (unsure if they're processed in sync bindings, I see it does have a "hidden" message loop in urlmon) since it's navigating away, so at least Gecko is "aware" of it.
Also what I meant is that at least I found it useful to test some behaviors of things required by MessageEvent.source, not itself; mostly related to ScriptHosts (that's how I found out about it in the first place), and of course we need SciptHosts fixed to be able to implement the CommandTargets that are ultimately needed for MessageEvent.source.
One weird behavior is, for example, "moving" the script hosts if they're on the initial (blank) window—this can happen if you obtain it via CommandTarget *before* loading the document via message pump, and it matches on the loaded document afterwards (but not after that).
