formatter removes end of document (...) directive.

I have yaml file like this:

---
tenantName: testTenant
actions:
- action: create
  objectType: tenant
  tenant:
    name: testTenant
...
---
tenantName: testTenant
actions:
- action: create
  objectType: attribute
  signal:
    name: helloAttrOld
...
---
tenantName: testTenant
actions:
- action: update
  objectType: attribute
  attributeName: helloAttrOld
  attribute:
    name: helloAttr
...
---
# similar things
...

But the auto formatter just removes the end of document directives (...) and only keeps the start of the document directive (---).
is there something that I can configure to get around it?

Environment: linux

Reproduce the formatter behavior in VS Code using the multi-document YAML example in the issue. Start by tracing the YAML formatter entry point and compare the formatted output with the input; done means preserving each document-end (...) directive while continuing to format the content.
