Specification

Verification Steps

Step 1: Create a static content (Either a page or static block) in Magento admin panel
Step 2: Use page builder to edit the content, drag and drop "Tab" inside a row
(Drag and drop the "Row" into the content area if it's not there already)
Step 3: Create multiple tabs to have toggle in storefront
Step 4: Save the content and check the tab(s) in storefront
(Configure the static block/page appropriately so that the content will be visible in storefront)

Current result:
Empty space will be visible on each tab switch

Fix result:
The tab content toggle will work and there won't be any empty space/in-active tab content displayed.
