This patchset adds XMLSerializer support and fixes several compatibility issues for Adobe Creative Cloud installer and similar applications. XMLSerializer implementation (mshtml) - Implements the `IXMLSerializer` interface with `serializeToString()` method - Allows JavaScript to serialize DOM elements to XML strings Embedded XML declaration handling (msxml3) - Adds CDATA wrapping for embedded `<?xml?>` declarations inside elements - Windows MSXML tolerates these nested declarations but libxml2 rejects them - The preprocessing step wraps problematic content in CDATA sections before parsing DISPATCH_METHOD|DISPATCH_PROPERTYGET fixes (jscript/mshtml) - Fixes ES5+ handling that was breaking method calls with arguments - When `cArgs > 0`, treats the call as `DISPATCH_METHOD` (actual method invocation) - When `cArgs == 0`, uses ES5+ behavior preferring `DISPATCH_PROPERTYGET` (property access) - In quirks mode (pre-IE9), returns `E_ACCESSDENIED` for `METHOD|PROPERTYGET` on function objects to match Windows Also added tests for XMLSerializer (empty elements, text nodes, special characters, nested elements, multiple children), embedded XML declaration handling (multiple declarations, deeply nested, encoding attributes, self-closing elements) and DISPATCH_METHOD|DISPATCH_PROPERTYGET behavior in both quirks and standards modes - Filip Bakreski -- v2: mshtml/msxml3: Add tests for XMLSerializer and embedded XML declaration handling. https://gitlab.winehq.org/wine/wine/-/merge_requests/10025
