Menu title doesn't get updated if I change the page title

[maaarsl]

It seems like WordPress converts the hyphen character to the dash character automatically. I created a new page with the following page title:

Foo - Bar

However, when I checked the menu title (Appearance > Menus), I found the title was displayed as:

Foo – Bar

The page gets stored in the database with a customized menu title (page title with a hyphen and menu title with a dash) and that's why the menu title doesn't get updated if I change the page title.

Twenty Seventeen: Ensure functions in customize-controls.js don't count on Customizer sections always being present

Before, the code assumed the theme_options section is always present, but it can be removed by plugins. This way, if it is, no JavaScript errors occur.

Merge of [39623] to the 4.7 branch.

Fixes #39355.

The revision [39632] mentions this ticket when it should have mentioned #39335.

This isn't a bug in the 'Twenty Seventeen' theme, it occurs with every theme. I think you got my bug description wrong.
