Theme Block Drafts Preserve Work More Reliably

Theme block drafts now preserve row state, relationship formatting, and saved field values more reliably. Reuploads and draft syncs are less likely to create duplicate fields or overwrite in-progress content.

What this fixes

Previously, theme block draft behaviour was one of the main sources of unpredictable content loss during active page-building sessions. Editing a block, saving a draft, and returning to find changed or missing content was a real risk.

The outcome for editors

Blocks can be edited, previewed, and refined without every nested field feeling fragile. The Website Builder is safer for real teams building real pages.
