1- If we use duplicate to add a div and pane to create a new tab, the preview of the new tab will not be displayed and we must reload the editor to solve it.
2- If we convert pane to flex, its content will be added inside all panes.
1- In the video below, I add a new tab and a pane. When I click on tab 3 in the editor, the preview is not displayed. When I reload the editor, the preview is displayed.
The tabs are hidden/visible by display: none and display: block. If you set the pane to display: flex, it’ll be flex all the time (which means they are visible all the time). The solution is to add a block or div inside the pane and set it to display: flex.
