[bug] Free end of a new edge position

[YanDoroshenko]

After clicking a port a new edge is being created with the free end (that is supposed to be at the cursor position) in the random location. An error is being logged to console:

Which browser was this on?

Can you re-test with latest git master (e2d990134b) / 0.10.1 ?

[YanDoroshenko]

Chromium 60.0.3112.101.
Firefox 55.0.2. Firefox does not log the error though.
Persists on 0.10.1 from NPM.

[jonnor]

Can confirm. When starting an edge, it is shown towards the place it the previous edge was dropped at - until a new motion event comes in.

I am seeing this with 0.11.1 as well.
