fix(label): adjusted basic labels height and attached image labels

basic labels have a border which increases the height in comparison to usual labels.
When inline together the line height gets increased
Because of that, a basic image label was not properly supported
All attached labels were not really attached to the boundary of a segment (as every other attached component is doing) . That was especially visible when a basic attached label was used
