Acceptance form field not visible in Chrome

Hi,
if I create a form using the Elementor Pro widget and I create an acceptance field (required) I can see correctly the empty little square in Firefox, while I can’t see it in Chrome.
The Elementor support team solved using the row:
input[type=”checkbox”]{ -webkit-appearance: checkbox; }
to be inserted in additional CSS, but they wrote also to me that: “I also suggest that you contact Ocean WP theme support and let them know about the issue as the issue is occurring because of some CSS they added.”
I add this topic just as an information.
