Chrome rendering unwanted inline style for <body> element


I’m having an issue with displaying my site in Chrome 81.0.4044.138

When rendered in Chrome, <body> has an inline style attached to it: style="transition: margin 0.25s cubic-bezier(0, 0, 0.3, 1) 0s;margin-left: 0px;"

This doesn’t happen in neither Safari nor Firefox. There isn’t anything set in the transition pane of the element and there aren’t any interactions.

Here’s the site live.

I’m really racking my brain here and I feel like I’m missing something obvious. Thanks in advance!
