Ported from #40758 (comment)

Steps to Reproduce:

class C
{
    public int Test1() { return 1; }
    public int Test2() { return 0; }
}

Execute Replace method with property on Test1

Expected Behavior:

class C
{
    public int Test1 => 1;
    public int Test2() { return 0; }
}

Actual Behavior:

class C
{
    public int Test1 => 1; public int Test2() { return 0; }
}
