Accessibility violation

[Natasha_Navarro]

Hello

Testing one of our Landing page with form we got accessibility violation about duplicated ID tag. This code was generated by Marketo twice on the page and it create an accessibility violation.

<style id=”at-markers-style” class=”at-flicker-control”>
 .mboxDefault {visibility:hidden;}
 </style>‍‍‍

Any idea what is it?

Thank you
