Target-typed switch expression doesn't handle typing well

[DoctorKrolic]

Similar to #73894, #81021

Version Used:
Latest VS 2026 [11201.2]

Steps to Reproduce:

class C
{
    public DateTime M(int i)
    {
        return i switch
        {
            1 => new($$),
            _ => default,
        };
    }
}

Start typing ticks at $$

Expected Behavior:
I get ticks: completion since it is one of possible constructor parameters

Actual Behavior:
When completion is invoked in empty parens, ticks: is in the list. If you start typing, it is not there.

This is the same as #81021 in its core: when there is an error , compiler bails out without trying to recover, thus type information of each switch arm is lost so IDE cannot determine completion based on type of new()
