"Open Link In New Window" from a container tab does not use the same container in the new window.

Actual behavior

Starting from a page in a container tab, right-clicking on a link and selecting "Open Link In New Window" will open the new page in a new window using the default tab.

Expected behavior

"Open Link In New Window" will keep the same functionality as "Open Link In New Tab", and the page in the new window will be opened in the same container as the original tab.

Steps to reproduce

1. From an existing Container Tab (without having set any webpages to always open in a container) right click a link
2. select "open link in new window"
3. observe that the window opens the webpage in a new window using the default tab.

You can modify this behaviour with Always In Container:
