✨ Modal side window background

[nelkor]

When you click on the background of the side window, it closes. And now it happens precisely on the event of pressing the mouse button, and not releasing it.

This can lead to bugs on some devices and browsers. For example, it can cause unintentional highlighting of text content on the screen.

We need to redo the side window so that the background is adjacent to the window itself. So that the closing of the window when clicking on the background occurs after an honest click event. After releasing the mouse button.

This issue seems to be irrelevant. We will come back to this if needed in the future.
