Unwanted error message appears: Chained designators are not permitted for a class type with a nontrivial destructor

Environment

• OS and Version: 13.6
• VS Code Version: 1.82.2
• C/C++ Extension Version: 1.17.5

Bug Summary and Steps to Reproduce

Bug Summary:
I have the following code that compiles without a problem with clang 15.0.0

struct Bar {
    float right, left, top, bottom;
};

struct Foo {
    std::string background;
    Bar padding;
};

Foo foo = {
    .padding.left = 3.f,
};

But on the line where I have .padding.left = 3.f, I get the following error in vscode only

[{
	"resource": "/Users/miguel/prototype/src/main.cpp",
	"owner": "C/C++: IntelliSense",
	"code": "3480",
	"severity": 8,
	"message": "chained designators are not permitted for a class type with a nontrivial destructor",
	"source": "C/C++",
	"startLineNumber": 28,
	"startColumn": 13,
	"endLineNumber": 28,
	"endColumn": 13
}]

Another odd thing is that if I remove the std::string background; then the error disappears

Steps to reproduce:
Copy the code above and vscode should complain

Expected behavior:
I don't get an error because the code works and compiles fine

No response

Reproduce the diagnostic in VS Code C/C++ IntelliSense 1.17.5 using the supplied C++20 example, clang compiler path, and macOS configuration. Trace the IntelliSense handling of the chained designator when Foo contains std::string, then verify that the valid example no longer reports error 3480 while invalid chained designators remain diagnosed.
