I haven’t noticed a pattern when exactly is this happening, but very often if I have a clickable element inside a builder, and I want to select it, it will follow the link and load a new page inside the Builder, without any warning.
Also, the back button in the browser is not working in that case, so I need to leave the page and enter into the builder again.
This mostly happens if the element is called by a shortcode, like a MEC event for example. But it also happened with standard Button elements.
Thanks!
