Description

The default icon for UCheckbox will not be bundled for client when SSR is disabled.

The check icon is missing:

and a warning message is shown in the console:

Warning

[Icon] failed to load icon `lucide:check`

fyi, the icon will show if

• provider: 'server' and ssr: true is set
• provider: 'iconify' is set and https://api.iconify.design/ is reachable
• Or, the icon is explitly specified: <UCheckbox v-model="value" icon="i-lucide-check" />
