[PATCH v14 0/2] MR3391: mshtml: implement window.MutationObserver with MutationObserver stub
This get us pass the "Update your browser" blocker in adobe's sign-in page. The page itself doesn't make use of `window.MutationObserver`.
However the sign-in page is still broken.
-- v14: mshtml: add stubs for MutationObserver methods mshtml: implement window.MutationObserver with MutationObserver stub

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=135260

Small nitpick, but you don't need try {} catch {} blocks for *successful* tests, just put the succesful test without any try/catch. If it fails it will generate an exception and the test will fail (but obviously, it shouldn't, so that's fine).

Are you sure this should be checked *before* validating `callback`? What happens if you write (in tests):
```jscript MutationObserver(42); ```

Small nitpick, but I'd honestly just merge this test with "MutationObserver" (just add it to the end of it), no need to make another separate test.

Yeah, that's what I meant, to make them stubs (so it's totally fine now).
As for your question about the array, you can't right now, it will need private interface and I have a lot of patches for that and to integrate jscript objects with mshtml ones (which is in Proton for example), but I need some revamps first upstream to get rid of some hacks as preparatory work before I try to upstream it.
Anyway it's nothing related to this MR so don't worry about it.
Anyway, other than those small nitpicks and (probably) moving the NULL result check (depending on the test you add), it looks good to me, now it depends on @jacek

but we would miss the helpful error message
