Why does opening the mobile menu (slideout.js) reset the scrolling of the window at the time the menu was opened?

Question

JavaScript

I am using slideout.js for a project . If you scroll the window and then open the mobile menu, the scrolling flies. As a result, you close the menu and find yourself at the top of the page.
Tell me what the problem is, please, if you have already encountered this behavior.

Answer 1

The problem is with these styles:

body, html {
    height: 100%;
    min-height: 100%;
}

Remove them and everything will work as it should.
