I'm reviewing my WordPress/Elementor page and can't determine what is causing a vertical hairline rule on the right side of my inserted Vimeo video link. I've inspected the native MP4 video that I generated from AE, and confirmed there is no background container/section fill or border. What would cause this. I'm using on a Mac running High Sierra OS 10.13.6 using WordPress 5.3.2 and the most recent version of Elementor. Thank you for any responses.
