sì, in effetti, sono stato un po’ sintetico.
quel browser supporta le grid-lanes, ma è dietro a un flag “sperimentale”.
l’avviso è innocuo e una volta che sposteranno quella funzionalità nella loro linea principale, scomparirà.
attualmente l’unico browser che lo supporta senza impostare un flag di funzionalità sperimentale è …
… Safari! (chi avrebbe pensato che Apple fosse la prima con uno standard? 
)
Se Horizon fosse meno presuntuoso e meno monolitico, otterresti qualcosa del genere:
Questa è una biforcazione molto approssimativa di Horizon, priva degli elementi invasivi e con CSS, TLP e Bars!.
Ovviamente ha bisogno di qualche affinamento…

Sembra un problema relativo al sidecar TLP. Darò un’occhiata.
Sembra un problema di compatibilità con il core … Lo risolverò per la versione pro del sidecar
Questo dovrebbe essere risolto da https://github.com/merefield/discourse-topic-previews-sidecar-pro/pull/183
Grazie, questo ha risolto il problema.
Ora è disponibile un’opzione di presentazione delle immagini in evidenza notevolmente migliorata: “Carosello”.
Consulta https://www.starzen.space/ per una demo
Ricevo questo tipo di errore nella console (ultima versione TLP)

Devi utilizzare almeno la v2026.8.0 
Di solito non do supporto alle versioni precedenti, ma aggiungerò un pin.
Fatto, ma dato che per te potrebbe essere complicato fare un rollback, la soluzione più semplice, a mio avviso, sarebbe aggiornare almeno alla v2026.8.0 (o alla v2026.9.x-latest).
