Start number of numbered lists

When I paste some texts from one of my plain text file and try to put it in markdown format, the numbered list is not displayed correctly.
Please find my texts below, it is correct here on issue page but it is not displayed correctly in macDown.
macDown version: 0.7.1 (870)
os: macOS Mojave 10.14.2 (18C54)

第一课 LED 闪烁

1. user_init()中创建一个任务：
   xTaskCreate(led_toggle_task, "led_toggle_task", 256, NULL, 1, NULL);

2. Initialise LED pin： GPIO14
   复制examples/driver_lib/driver/gpio.c 复制到项目的driver文件夹，把examples/driver_lib/include/gpio.h复制到项目的include文件夹
   设置头文件包含 #include "include/gpio.h"

void led_init( void )    
{
	GPIO_ConfigTypeDef  GPIOConfig;

	GPIOConfig.GPIO_Pin = GPIO_Pin_14;
	GPIOConfig.GPIO_Mode = GPIO_Mode_Output;
	GPIOConfig.GPIO_Pullup = GPIO_PullUp_EN;
	GPIOConfig.GPIO_IntrType = GPIO_PIN_INTR_DISABLE;
	gpio_config( &GPIOConfig );	
}

3. 进行 GPIO toggle

void led_toggle( void )
{
	uint32_t bit;
	
	bit = GPIO_INPUT_GET( 14 );
	
	GPIO_OUTPUT( GPIO_Pin_14 , bit ^ 0x00000001 );
}

4. 任务调度

Reproduce the pasted numbered-list example in MacDown 0.7.1 on macOS Mojave, comparing its rendering with the GitHub issue-page rendering and the linked screenshot. Trace the Markdown rendering path responsible for numbered lists; done means the supplied example displays its list numbering correctly in MacDown.
