Customizer: Fix click.preview event handler for jump links and shift+clicks in preview.

Browse Source 
* 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 (#32681) to just focus on the control in the Customizer.

Fixes #26005.
