Naming suggestions fail to correctly identify private members that lack the privatemodifier.

[severity:It's more difficult to complete my work] [regression]
If you want to declare a private field of type intbut do not prefer to add the privatemodifier, the naming suggestions provided when typing the type intwill follow the style for public members. If the privatemodifier is present, the correct suggestion is given. I have ruled out the influence of extensions.

This bug likely emerged in recent versions of VS2026, as I've never noticed this issue before.

if `private` exists, it is correct.

Additionally, there is another issue: when a class or struct implements IDisposable, the naming suggestion inexplicably always recommends naming it IDisposable.

Reproduce the naming suggestions in VS2026 for a private field without the private modifier and for a class or struct implementing IDisposable. Start by tracing the Roslyn naming-suggestion behavior from those cases; done means both cases recommend the appropriate naming style rather than the public-member or IDisposable name.
