What problem does this address?

When searching for pages in the Navigation block's page search input, the browser's autocomplete dropdown appears and obscures Gutenberg's own UI suggestions.

This creates a confusing user experience because:

• Browser autocomplete shows irrelevant search history from other websites
• It visually clutters the interface and blocks Gutenberg's page suggestions
• Users may not know which dropdown to interact with (browser vs. Gutenberg)
• The browser suggestions are rarely useful in this context (site-specific page searches)

This is especially problematic for first-time users who expect a clean, focused search experience when looking for their site's pages.

What is your proposed solution?

Add autocomplete="off" to the search input field in the Navigation block.

This would:

• Prevent browser autocomplete from appearing
• Keep the UI clean and focused on Gutenberg's page suggestions
• Improve visual consistency with the rest of the block editor
• Reduce user confusion by showing only relevant, site-specific results

Where to implement:
The search input that appears when adding blocks to a Navigation block.
