problem with v2.4.3

When the page loads it renders correctly, but when the user clicks a tab to display content, the <iframe> (youtube video) embeded outside a WP Tab disappears from the front-end. (iframe inline style changes to style=”display: inline-block; width: 0px; height: 0px;”)

it occurs with the last plugin version

[my wp current version: 6.1.1]
