Have this odd quirk — possibly a hangover from me trying to build a custom menu — where when I open the navbar menu the icon vanishes, which I’m thinking might be a z-index issue, even though I’ve hard-set the values. It works fine in the designer, apart from when you preview it (and live).
Can anyone diagnose the issue? I’m scratching my head so much I have a bald spot.
