What problem was encountered?

Sync CopyFromUri does not copy tags from the source blob. It does not appear to respect the x-ms-copy-source-tag-option header.

Furthermore, when x-ms-copy-source-tag-option is supplied as COPY, a 409 is supposed to be returned if any tags are specified via x-ms-tags.

Instead, in both cases tags specified via x-ms-tags are set on the new blob and original tags are never copied.

Steps to reproduce the issue?

Invoke Copy Blob from URL, passing x-ms-copy-source-tag-option=COPY with a source blob that has tabs set.

Also:

Invoke Copy Blob from URI, passing x-ms-copy-source-tag-option=COPY and also specify x-ms-tags and note that no 409 is returned and the tags specified in the request are set.

Have you found a mitigation/solution?

Copy the tags in a seperate operation, or retrieve them ahead of time and pass them via x-ms-tags
