While working in a new theme for EB (most recent version), we noticed what seems to be a glitch between our template and the slider theme during certain larger responsive behavior.

Please have a look at

Notice how after 993viewport the container becomes really high and empty ?

Our programmer said this was a bug between the theme and the template (probably something due to JS) ? Honestly, I have no clue, i'm just passing on the message here ;-)

Can you see why this is happening ?

Thanks
