'Replace' and 'Fail' Conflict Behaviors Not Working as Expected in 'driveItem: copy'

Expected or Desired Behavior

When using 'fail', the operation should fail and report a conflict if an item with the same name already exists in the destination folder.
When using 'replace', the operation should overwrite the existing item at the target site if there's a conflict.

Observed Behavior

@microsoft.graph.conflictBehavior=fail

Steps to Reproduce

Open Microsoft Graph Explorer.
Execute the following POST requests using Graph Explorer: POST /sites/{siteId}/drive/items/{itemId}/copy?@microsoft.graph.conflictBehavior=fail POST /sites/{siteId}/drive/items/{itemId}/copy?@microsoft.graph.conflictBehavior=replace
Verify whether the expected changes (failure or replacement) are reflected in the destination folder.
