Does the width set by setBlockEditorWidth persist across sessions?

Does the width set by setBlockEditorWidth persist across sessions?

• A. Yes, it persists automatically.
• B. Width persists across sessions.
• C. It persists only while the block is open.
• D. No, it doesn't persist; must set each time the block is opened.

Answer: (D)

When you adjust the editor width with this function, you’re changing a UI setting for the current editor instance. It’s a runtime state, not something that’s saved to your account or stored by the editor itself. Because there’s no built-in persistence for that width, opening the block again loads with the default width instead of the last value you set. If you need it to stick across sessions, you’d have to implement your own persistence—save the chosen width somewhere (local storage, a backend, or user preferences) and re-apply it with setBlockEditorWidth each time the block opens.
