Suppose we are visiting a Single Page Application(SPA), which url on the browser is "https://xxxxxxx.com/home/self". Since this is a SPA, website server has no real html located in 'https://xxxxxxx.com/home/self', it just has a single html, which located in 'https://xxxxxxx.com', as for other path such as 'home/self', it is just html5 history api.


```
documentClone.adoptNode(this.documentElement)
```

Let me explain more:

documentClone is just a empty page, which html structure is like: `<html><head></head><body></body></html>`.

this.documentElement is another document, and we can suppose it is loaded from another website page, we call it Page A later.
Page A is a Single Page Application, which url is like: "https://xxxxxxx.com/home/self".
this.documentElement has a `<img>` child, which structure is like "<html> ...   <img id="img" src="assets/aa/bb.png">    ...</html>".


Befor calling `documentClone.adoptNode(this.documentElement)`, when i run `this.documentElement.getElementById('img').currentSrc`, it will return "https://xxxxxxx.com/assets/aa/bb.png".
After calling `documentClone.adoptNode(this.documentElement).getElementById('img').currentSrc`, it will return "https://xxxxxxx.com/home/self/assets/aa/bb.png"

Other browsers will return "https://xxxxxxx.com/assets/aa/bb.png", and before Safari 15.4(MacOS)  it will return "https://xxxxxxx.com/assets/aa/bb.png". But for  Safari 15.4(MacOS), it will return "https://xxxxxxx.com/home/self/assets/aa/bb.png". Maybe this is produced along with Safari 15.4 release.
