HTML (image) stopped working in name property on Github pages

We had a logo top left using HTML embedded in the name field but it's suddenly stopped working in Github pages.

```js
window.$docsify = {
 name: `\
 <svg width="136" height="28" xmlns="http://www.w3.org/2000/svg">\
 <g fill="#D90268">\
 <path d="..."/>\
 </g>\
 </svg><br>\
 Our custom header`
}
```
