Wrong behavior, but i dont think it is wrong enough to label it as bug.
- Tabs from external apps opening in last used container instead of default container.
- When you type url assigned to specific container, you dont get to that webpage if you was in other container. Webpage opens, but you have to navigate to it in tab list. For example, you are in tab 1 of container 1. You open adress bar and type in "website.com". If you have website.com assigned to container 2, after hitting enter you will not visit website.com. It will get opened in container 2, but you will stay in container 1. Same happens if you open link in new tab.
