Move static members to another type... refactoring is unhappy with partial classes

**Version Used**:
VS 2022 17.14.11

**Steps to Reproduce**:

1. in a partial class where multiple documents have static members, open the `Move static members to another type...` refactoring from the Ctrl+. context menu for one of those static members

2. select all members in the upcoming dialog - this picks members from multiple files, hit OK
3. observe the error and the golden bar complaining about the node to track not being a descendant of the root

**Expected Behavior**:
no error, each member should be moved into one type

**Actual Behavior**:
the error message comes up and nothing is modified.

**Notes**
Moving the individual static members into one new type step by step worked, so i suppose it has something to do with the `partial`ness of the source.
