Last Column In Editor Hides Under the Silder

OS: OSX 10.11.5
Deco: 1.1.2 (0.6.0)

As soon as a file has enough rows to activate a vertical slider, the slider covers up the last column in the editor, disallowing the ability to see the last character in the row. When the last character is a single/double quote, anyone unaware of this issue could easily think there a missing closing quote.

An example:

When the slider doesn't cover the row, you can see the covered characters as well as the cursor:

Addendum:

Also issues with bottom slider. Will want to make sure both sliders do not cover the editor area. Explanation of bottom slider behavior in later comment below.
