pinning session tab opens a newtab

[LaurenWags]

Description

If you drag a session tab out into its own window and try to pin it, the tab doesn't pin and a new tab (with the same session #) opens in the original window.

Steps to Reproduce

1. Launch 0.22.103 with a clean profile
2. Open a session 1 tab and navigate to a site (I used twitter)
3. Open a session 2 tab and navigate to a site (I used twitter)
4. Drag the session 2 tab out into its own window.
5. Try to pin the session 2 tab

Actual result:
session 2 tab is not pinned, a new tab is opened in the original window:

Expected result:
session 2 tab should be pinned

Reproduces how often:
easily

Can't reproduce on current dev so I think this will be fixed in the next build. Let's verify when that is available.
