Installing extension: Dependency Window has a Back Button which is not working
If you try to import an extension that depends on an extension that's not installed yet, you have the "import now" option.
After opening the popup and installing the needed extension, you have the link to close the popup. This link is working. But in the top left corner of that window there is the button "Back". This one is not working. If you click that option, the popup will not close, but it shows the content of the extension manager in the popup.
