Size property not changing in the properties window when using AutomaticSize

So, I have the problem that, when I use AutomaticSize on the X axis on a text label and then typing something into the text label, AutomaticSize doesn’t change the size property in the properties window (picture). Did I something wrong or is this just a bug?

AutomaticSize edits the size of the frame but not the Size property (the raw size of the frame). If you want to get the size, use AbsoluteSize instead.
