Description

While using Atom on relatively large monitors, the auto-complete popup doesn't line up with the cursor position once the current line length reaches a certain width:

This started happening on Atom 1.17, presumably due to the changes in https://github.com/atom/autocomplete-plus/commit/19f68fe36aebd8cfd8bc1b065baadbd64e7fb694.

A possible workaround I've found is to set autocomplete-suggestion-list .left-label to max-width: 10vw;, rather than the current value 20vw.

Steps to Reproduce

1. Open Atom 1.17.2 on large screen, e.g 3440x1440
2. Get autocomplete popup to show up.
3. When the cursor goes beyond a certain column location, the autocomplete popup becomes mis-aligned.

Reproduces how often: Always
