Multiple groups are open after renaming the workflow file in VSCode

Multiple groups are open after renaming the workflow file (sw.json, sw.y(a)ml) in VSCode.

Steps to reproduce

1. Open a workflow. For example: hello-world.sw.json

2. Rename it, but keep the sw.json extension. For example: hw-renamed.sw.json

Actual result

The file is open in a new group, which results the same file opened in three groups simultaneously.
See:

Expected result

Nothing described above happens when renaming the file. Only the remaining itself.
Text editor is shown in the left group, and the diagram is shown in the right group.
