 If I set an SVG image as my logo in the customizer, my debug log gets
 filled with the following notices:

 ``` PHP Notice:  Trying to access array offset on value of type bool in
 /{redacted}/wp-includes/media.php on line 1182 ```

 Looking at that file, that section refers to the following function:

 function _wp_get_image_size_from_meta( $size_name, $image_meta ) {
         if ( 'full' === $size_name ) {
                 return array(
                         absint( $image_meta['width'] ),
                         absint( $image_meta['height'] ),
         } elseif ( ! empty( $image_meta['sizes'][ $size_name ] ) ) {
                 return array(
                         absint( $image_meta['sizes'][ $size_name
 ]['width'] ),
                         absint( $image_meta['sizes'][ $size_name
 ]['height'] ),

         return false;

 I suspect what's happening here is the function is assuming there will
 always be a height and width meta, which doesn't exist with SVG file
