Arrows in sequence diagrams are drawn slightly out of position

[simonborje]

Description

When a sequence diagram with at least two levels are drawn the line and arrow heads that connect the second (or later) level with the next is placed slightly too high compared to the "activation box", leaving a small gap between the box and the arrow. The lines connecting the first level and the second level looks good on the other hand.

Additionally, the arrow heads themselves look like they are missing the top "corner" as illustrated in a screenshot below.

Steps to reproduce

Use code sample and observe line/arrow positions.
