Fixed

• Tab icons with a prefixed name (tabler:bug, bi:gear) render only with an icon set that has them: ux_icon,
  or the matching font set (tabler-icons / bootstrap-icons) without the prefix. With any other set the tab shows
  its label only, instead of a broken bi bi-tabler:bug class (bundles pass Tabler names to every host).
