Style issues with Safari

I'm embedding a page into an APP developed with Xcode through WKWebView, but I've encountered style issues with the page rendered by WKWebView.

I simplify the problem as follows.

Open this link with Safari:

https://cofficlab.github.io/JuiceEditor-Playground

What is the light blue part?
How can it be removed?
If this is a feature, what is the name?

Chrome doesn't have this problem.

I forgot to mention a crucial step. After opening the link, you need to click on the green button(which is actually an image).

Hi,

You should be able to add CSS for your button and hide this.

The question is: what CSS code should be added? If this is a feature, what is the name?

There is no such problem in other browsers.
