[BUG] push-menu.ts uses 'touchstart' in non-passive mode

[WalterB-MAMC]

The developer console reports the push-menu.ts files uses of touchstart as an issue as it does not allow for passive mode. This is a scroll-blocking event and makes the page less responsive. It needs {passive: true} to be added to the event listener like the following:

sidebarOverlay.addEventListener('touchstart', '{passive: true}', event => {
    event.preventDefault()
    const target = event.currentTarget as HTMLElement
    const data = new PushMenu(target, Defaults)
    data.collapse()
  })
