Line visible on left of the mobile menu container

[KaichenWang]

I noticed a line to the left of the mobile menu container. It appears attached to the "transform: translate(0)" (see screenshot). To replicate, go to the mobile view in your theme editor.

.no-js details[open]>.menu-drawer, .js details[open].menu-opening>.menu-drawer, details[open].menu-opening>.menu-drawer__submenu { transform: translate(0); visibility: visible; }
