<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Customizer: Fix `click.preview` event handler for jump links and shift+clicks in preview.
* Prevent following jump links (starting with `#`), but instead scroll that element into view.
* Prevent following links clicked in the Customizer if shift key is pressed when clicking; this fixes an issue when trying to shift-click on a widget or nav menu item (<a href="https://core.trac.wordpress.org/ticket/32681">#32681</a>) to just focus on the control in the Customizer.
Fixes <a href="https://core.trac.wordpress.org/ticket/26005">#26005</a>.</pre>
