Shortcodes in Tabs not working

Hello,

Using 3rd party shortcodes inside tabs does not work! You can see an example here:

It works for the first tab or the active tab but not for the others. I suspect it is because the content on each tab needs to be loaded when the tab is clicked and not just on page load.

Is there a solution for this?
