 On the $wp_customize object, passed via the 'customize_register' action,
 the get_section, get_panel, add_section, and add_panel functions allow
 strings that contain either hyphens, "-", or underscores, "_". However,
 when using the remove_section function, sections whose ID contains hyphens
 are not properly removed, and instead the entire Customizer is empty (no
 sections) and thus broken. No PHP errors or warnings are thrown in my
 case, and I can reliably reproduce the error and contrast it with sections
 added and removed in the exact same way but with IDs containing
 underscores instead of hyphens. Calling remove_section on a non-existent
 section, even one that contains hyphens, like 'bogus-fogus', does not
 reproduce the break; It only seems to happen when trying to remove
 sections which actually exist.
