There seems to be an unresolved issue with the native Webflow Tabs. I have linked to a forum post I created a while back that provides insight into the problem but I want to ask the community if they have been able to find a work around for the problem.
The problem: Custom Code does not executed on load when not in the active tab.
I’m having a similar issue with height. Using a Shopify Buy Button, only the active tab loads auto height based on content. It’s driving me batty, did you come up with a solution?
I have hunted everywhere and your problem is the closest problem, but no answer.
