When the context menu opens (
htmlEl.focus()) and especially when it closes and restores focus (previousFocus.focus()), the browser runs its default scroll-into-view on the focused element. In any scrollable host layout this yanks the whole page - the panel scrolls out of view, the minimap jumps toward the center, and the canvas appears to shift ~200–300px on every menu dismiss.The fix is to pass
{ preventScroll: true }to these.focus()calls so focus is moved without scrolling.
