Hello,
1) Keep this option disabled in the Elementor plugin settings https://prnt.sc/26kutaf It causes the issue with the image lightbox. Check now.
2) Safari displays icon in this way even with the default Twenty Nineteen WP theme https://prnt.sc/26kuwz4 So, we can do nothing with this, unfortunately. Read this post https://devmaverick.com/svg-gets-cut-off-on-ios-safari-and-chrome/ and try solution described there for your custom icon.
Regards
