Can anyone else repeat the following?

Step A:
1. Create a simple line.

2. Ctrl+C (copy to clipboard)

3. Change the outline color of the selected line so it will be easily discernable from a pasted copy.

4. Ctrl+Shift+V.

NOTE: the two lines align themselves precisely.

Step B:
1. Create a simple line but this time apply an ArrowHead.

2. Repeat steps A.2 through A.4.

The two ArrowHead lines do NOT align.
