Inlay hint flicker when adding/removing whitespace around it

[Altonss]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: VS Code 1.94.2 (Also reproduced on VSCodium 1.94.2)
• OS Version: Fedora Linux 40 (Workstation Edition), Gnome (46), Wayland

Steps to Reproduce:

1. Create a test.ts file
2. Enable typescript.inlayHints.functionLikeReturnTypes
3. Write:

function foo(){
    return Date.now();
}

4. Change to: (adding a whitespace between foo() and {)

function foo() {
    return Date.now();
}

5. During the change you will see a small flicker of the inlay hint: going from : number to : numbe... to : number again.

This flickering behavior isn't very elegant, and also happens with other languages, for example with Python (and the basedpyright extension, see https://github.com/DetachHead/basedpyright/issues/794)
