Bug Report

When window.$docsify.logo is set, window.$docsify.name does not get escaped properly.

Steps to reproduce

1. mkdir test && cd test
2. docsify init . && docsify serve .
3. set window.$docsify.name to " and window.$docsify.logo to a random image.

What is current behaviour

It sets it as raw HTML value instead of the alt text.

<!-- 'window.$docsify.name' -> 'hello test"'-->
<!-- 'window.$docsify.logo' -> 'https://upload.wikimedia.org/wikipedia/commons/thumb/3/3a/Cat03.jpg/1200px-Cat03.jpg"'-->
<img alt="hello" test"="" src="https://upload.wikimedia.org/wikipedia/commons/thumb/3/3a/Cat03.jpg/1200px-Cat03.jpg">

When no image is provided, it does get escaped properly:

What is the expected behaviour

Correctly escaping " to " and others (space, etc) or using escaping it using something else.
