LatticeTabs: `tabs` changed (a label, a badge or a descriptor), but the strip takes it only when created - the module has no way to repaint an existing tab. Nothing was applied and the strip was NOT rebuilt, which would have lost whichever tab is open and any state its content holds. Wrap the strip in an `{#if}` you toggle when a genuine rebuild is wanted; a live badge otherwise belongs in your own markup.

What happened

The Svelte tabs component received a different tabs array from the one the strip was built with. As in every adapter, the tabs module reads the descriptors once; there is no API to repaint a built tab, so nothing could be applied, and the strip was left alone rather than being rebuilt behind your back and closing the open tab.

The fix

Toggle an {#if} or {#key} around the strip when you genuinely want a new one. A badge that has to track live data belongs in your own markup, outside the strip.

The smallest fix

{#key tabsRevision}
  <LatticeTabs {tabs} bind:active />
{/key}
