**Note**
* When a smaller browser window is used and a comment pop-up is opened, it might spill out of the window. A horizontal scrollbar is not created to accpunt for the spillout.
* This issue more likely occurs when the comment is placed in the middle of the page because it opend to a side or another. In this case, our suggestion would be to center the pop-up in the available wiewport and add a horizontal scrollbar to compensate for further spilling.
