User agent stylesheet overriding some biome mission div style.display attributes seemingly at random after long periods of browser tab inactivity

Honestly not sure why this is happening or how to fix it other than doing something like this which I think would be very dirty and yucky

        document.addEventListener('focus', () => {
            function biomeMissionsDivFix(div) {
                let h2s = div.querySelectorAll('h2')
                for (let i = 0; i < h2s.length; i++) {
                    let h2 = h2s[i]
                    let subDiv = h2.querySelector('div')
                    subDiv = subDiv.querySelector('div')
                    if (subDiv.style.display != 'block') {
                        subDiv.style.display = 'block'
                    }
                }
            }
            let curr = document.getElementById('current')
            let upcom = document.getElementsByName('upcom')
            biomeMissionsDivFix(curr)
            biomeMissionsDivFix(upcom)

        });

Edit: Ok I think it was a bug with the browser itself (Google Chrome). I noticed it had begun happening every time I tabbed over in both incognito and a normal profile, and I opened the site in Vivaldi and it wasn't happening there. I guess it makes sense because my session was days if not weeks old. I'll keep monitoring and see if I feel like putting a head style dom element refresh fix for it, but I'd rather google would just get it together honestly, and I don't liek the idea of 304ing the stylesheet every visibility change so it'll have to go into session/local storage too.
