SA1101 in property pattern

[JohanLarsson]

internal object? P=> this.Value switch
{
    InvocationExpressionSyntax { Expression: LiteralExpressionSyntax { Token.ValueText: { } valueText } } =>null,
    _ => null,
};

Happens right after IDE0170 "simplify property pattern" - a C#10 feature?

BTW a simple if is enough:
if(something is { Page.PageNumber: > 1 })
