Interface type is not offered in completion list while typing declaration of an explicit implementation for a static member

[AlekseyTs]

interface I1
{

    static abstract void M1();
}

class C1 : I1
{
    static void 
}

Press 'space' after static void in C1.

Observed:
No completion list offering I1 for explicit implementation.

Expected:
I1 is offered as it is done for instance members.

Note, properties, events, operators and conversions are affected as well.
