Description

related to #41549

• block background color is different between Site Editor view vs Front side
• description is mandatory : people cannot only set the search icon within the nav
• if no description is set, the search block takes too much place !!! and there is no way to reduce its width (just display the icon)
• border is always visible

IMHO, a quick improvement is needed for 6.2 for user UX, to make it usable / clean (to not make any new WP user angry)
ping @annezazu (FSE Outreach)

Step-by-step reproduction instructions

Just add the search block within the nav component (here in the header partial part)

Screenshots, screen recording, code snippet
