[PATCH v3 0/10] MR4285: jscript/mshtml: More leak fixes.
-- v3: mshtml/tests: Fix BindInfo leak in htmldoc test. jscript/tests: Fix Date object leak in test_default_value. jscript/tests: Fix variant leak after conversion when testing jscript: Fix value arg leak in transform_json_object. jscript: Don't addref before calling jsdisp_propput_name. jscript: Fix array leak in Array.filter. jscript: Fix value leak in Array.shift. jscript: Fix EnumVARIANT leak in enumerators. mshtml: Fix window leak on error in async_stop_request. mshtml: Release the returned lists from Gecko's QuerySelectorAll even https://gitlab.winehq.org/wine/wine/-/merge_requests/4285
From: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> Gecko may return a pseudo-element-list even on error (such as with an invalid selector, for example), which holds refs to elements and leaks.
