Version 1.7.15 add a hidden tag and what is this exactly do and why needed?

<div style="position:fixed;top:1px;left:1px;width:1px;height:0;padding:0;margin:-1px;overflow:hidden;clip:rect(0, 0, 0, 0);white-space:nowrap;border-width:0;display:none"></div>

Yeah this is annoying me too because it slightly effects SEO/page speed in a negative way. Can I have this tag use tailwind classes instead of the style attribute?
