Repro code
A property with [Editor(MultilineStringEditor)] and with null value: the edit
drop-down arrow appears but the editor doesn't appear when it's clicked. Type
some text into the field, confirm the edit -- hit return, or click in another
field and back, etc -- and hit the drop-down again, the editor now will appear.
Repro attached, property "FooStringMultilineEditor".
Fix is:
[[

if (editorService != null)

null))
return value;
editContent = value as string;

Note that results in null being returned as String.Empty when no change is
made, but that matches MSFT -- and good properties don't return null anyway.
