Background of nested section leaks to section

[Martinomagnifico]

Since 5.0.0 there is a flash of color when navigating between slides, when a nested section in the second stack has a custom color. It happens only the first time, and no longer when going back and forward. I've tried to change backgrounds.js, but can't get it to work without breaking the backgrounds that are set with a data-attribute. See this pen: https://codepen.io/martino/pen/eYxvjQV

Thanks for reporting @Martinomagnifico! Fixed this in 1e1e228 and released v 5.0.2.

Give it a try when you get a chance.

Thanks for the fast fix! There is still a 'present' class in a (nested) background that is in the future though. But the flash is gone :-)
