Ui Extensions: `<GridItem/>` vs `<s-grid-item/>` regressions

While working on our React to Preact migration, we’ve hit roadblocks for this component.

React: GridItem
Preact: s-grid-item

Would it be possible to address the following regressions?:

  • columnSpan and rowSpan - Replaced by gridColumn and gridRow. They have lost its MaybeResponsive signature, this used to allow for fine-tuned templates that were responsive. Could we restore this regression?

Checks:

  • Docs, confirm regression.
  • IDE, confirms regression.
  • Trying to implement, confirms regression.

Context:

  • @shopify/ui-extensions-react: 2025.7.3
  • vs
  • @shopify/ui-extensions: 2026.4.0

Thank you very much!
