Pinned tabs moved to new window

[jhouska]

Describe the bug
I have created several groups of tabs. There are several pinned tabs that are in all tab groups. Quite often when I click to a pinned tab, it is removed from the group and moved to a new window.

To Reproduce
Steps to reproduce the behavior:

1. Create more tab groups
2. Pin a tab
3. Click on the pinned tab

The tab is removed from the group and moved to a new window.

This problem occures several times in an hour.
