Modal accessibility role "none"

[davidnixon]

tabbable element's role 'none' is not a widget role

Detailed description

I'm having accessibility issues on component. After scanning, it return the following error:
The tabbable element's role 'none' is not a widget role
A tabbable element must have a valid widget role
Element location:

<div
    style="position: absolute; height: 1px; width: 1px; left: -9999px;"
    class="cv-modal__before-content"
    tabindex="0">

When running IBM's Accessibility checker scan in the same component on Vue's storybook from Carbon I've got the same error.
Have anyone had this issue before? Does anyone knows if this violation is associated with any version of @carbon/vue version?
Thanks in advance! 🙂
