Active class not being applied to link

[Reached]

Hi cferdinandi,

Really great work on this plugin (and smooth-scroll), it's really easy to use! However I have ran into an issue. I have four links in my navigation bar like this:

<div class="links-right" data-gumshoe>
                    <a data-scroll href="#intro">Intro</a>
                    <a data-scroll href="#about">About</a>
                    <a data-scroll href="#services">Services</a>
                    <a data-scroll href="#contact">Contact</a>
                </div>

It applies the classes correctly when I scroll, however it's skipping the #services link for some reason.

The markup for each section is like the following:

<section class="services-section" id="services">
            ...
</section>

To better explain whats happening, i made a short video showing it. Do you have any idea what's causing this? :)

Hi there - can you toss the video up on YouTube or Vimeo? For security reasons, I don't download files from people I don't know. Thanks!

Or better yet, a reduced test case where I can actually look at the code in a working environment would be great.

That is completely understandable :).

Here is a link: https://www.youtube.com/watch?v=1AIVa3ZGZOg&feature=youtu.be, quality is bad, but should be able to see what happens.

If this is not enough, I can provide some more code :)

Just from looking at it, it could be that the script thinks your at the bottom of the page (and therefore activates the last link). BUT... could be something else. If you were able to setup a working (or failing, in this case) example I could look at, that'd help me debug.

Hi again,

I just tried to set the height of each of my sections to a 1000px, that solved the problem.. So I guess you were right about the script thinking I was at the bottom :).

Thank you!

Cool. The reason I do that is because I was running into edge cases where the last section was fully on screen, but the section before it was too and so the last section never went active. I noticed a few other ScrollSpy scripts used the same approach (most notably, Bootstrap's) and went with that.
