Not sure if this is an issue or simply a request for clarify me how the code is working, is not easy to me to understand the logic behind the library (hint: maybe some comments could help! 😄 )

I've an issue in another project that use scrollparent.js as a dependency (see gilbarbara/react-joyride#376).

After lot of debugging the issue seems related to the management of CSS overflow that is done here:

I'm trying to understand how this should work, why overflow is special for you, as every DOM element that use overflow are giving me issues.

Any tips will be appreciated!
