Signature help does not appear for target typed new with partial parameter

This issue has been moved from a ticket on Developer Community.

[severity:It's more difficult to complete my work]
When a constructor is invoked for a class type that is defined by a function's return type, intellisense does not display the constructor's parameters. In the first screenshot (return new (...), I am attempting to open the intellisense by pressing Ctrl + Shift + Space, but nothing opens. In the second screenshot (return new MyClass(...), I am able to open the intellisense by pressing Ctrl + Shift + Space to see the constructor takes one string.

Specifically the difference here is that invoking cntrl+shift+space when using the target typed new constructor does not work when the parameter is partially input

Does not work at caret ($$)

public class MyClass(string arg) { }

public MyClass Example1()
{
    string test = "";
    return new(tes$$)
}

Signature help works at caret ($$):

public class MyClass(string arg) { }

public MyClass Example2()
{
    string test = "";
    return new MyClass(tes$$)
}
