Trying to import a gzip sql file and it gets stuck on "Parsing SQL file, please wait". Here is the error thrown in the logs.

This helps to resolve the issue:

public function file_is_gzipped( $file ) {
    $is_gzipped = false;
    if ( ! $this->filesystem->is_file( $file ) ) {
        return $is_gzipped;
    }

    $mime = wp_check_filetype( $file );
    if ( false === $mime['type'] && function_exists( 'mime_content_type' ) ) {
        $mime['type'] = mime_content_type( $file );
    }

    if ( in_array( $mime['type'], array( 'application/x-gzip', 'application/gzip' ) ) ) {
        $is_gzipped = true;
    }

    return $is_gzipped;
}
