**Steps to replicate the issue** (include links if applicable):
On en:wp, when using Vector 2022: click "Switch to old look" in the left sidebar and try to switch.
**What happens?**:
* I am taken to the "Skin" preferences section, and have to figure out to click on Vector 2010, scroll down, and click Save
* After saving, I am still on that preferences page, with the changes applied, and have to manually navigate back to the page I was on before
**What should have happened instead?**:
* A one-click change back to my previous skin selection, while staying on the page I was reading. (what I thought the on-wiki discussion was pointing towards; I didn't find another phab task for this)
(In the same conversation, I thought that Vector 2010 would also have a persistent "Switch to new look" link in the same place in the sidebar, making it easy to switch back and forth; see T327466)
