Pantheon-mail jumps to the message beginning at the first click at its body

[Evgenii Frolov]

Any time I read an e-mail in Pantheon-mail and click (a link or something) I get all the mail scroll (up or down) to the beginning of the mail body.

For example, if I open a new e-mail (upper half of the image) and JUST CLICK the viewer will jump from the very top to the beginning of the mail body (down half of the image).

This is true for both right, middle and left click. This is true for only the first click per message.

Steps to reproduce:
1. open an e-mail in Pantheon-mail
2. right/middle/left-click anywhere in the mail body

Expected:
popupmenu for right click and nothing happening for middle and left click

What actually happens:
The viewer jumps to the beginning of the message body.

Additional info:
This takes place only for the first click after opening a message. Clicking one more time in the same message does not cause the "jump-to-beginning".
Opening another message causes this problem again.
