Can you provide a little more info - perhaps examples/screenshots. I'm struggling to get a clear understanding (probably more me being dense than anything else).
Are you saying that significant whitespace as opposed to insignificant whitespace is being removed from within an annotation tag? Or do you mean something else?
if this helped answer the post, could you please mark it as 'solved'? Also if you consider whether the title of your post is relevant? Perhaps if the post is solved, it might make sense to update the Subject header field of the post to something more descriptive? This will help people when searching for problems. Ta
