Comment:

 Thank you @adamsilverstein for investigating the issue. It helped me a lot
 to find out what was wrong and create
 [https://core.trac.wordpress.org/attachment/ticket/38948/38948_1.diff a
 fix]. You can also review it [https://github.com/xwp/wordpress-
 develop/pull/209 on the GitHub].

 So the issue was that the `initSortables()` has been called before the nav
 menu section was actually expanded. Because of that incorrect
 `offset().left` value has been calculated (as noted by @adamsilverstein:
 instead of `0` it returned `299`).

 The `initSortables()` method call has been bound to the `expandedSection`
 event, so that the calculation is done after the section is fully
 expanded. It fixed the issue on my end.
