Customizer: Display section descriptions like sidebar descriptions

[obenland]

When adding a section to the Customizer, it offers the possibility to add a description of this section. Currently this description gets output as in a title attribute to the h3 headline of this section - and is completely hidden and gone. :( Or did you know we have a four line description of the navigation section?

It would be awesome if we could move that more in the user's view, maybe like how we currently do it for widget sidebars?

The menu description - actually visible.

Yeah, I'd consider that a bug :) +1

Replying to SergeyBiryukov:
Thanks Sergey, I was looking for a Customizer component but had no luck ;)

Never noticed that. Looks good. :-)

The esc_html() seems unnecessary.

Updated patch.
