The current codebase carefully synchronizes all access to MutableSpan where there can be concurrent use. We missed a spot where Tag.tag is not synchronizing access. The only other place we don't guard is ScopedSpan, which is documented explicitly as not thread safe. Fixes #1384 Signed-off-by: Adrian Cole <adrian@tetrate.io>
