Good find. Disproves the "only useful for web fingerprinting". It's also useful to their users for a fairly common flow.
Don't assume malice, but do consider side effects of your decisions.
This does add an extra bit to web-fingerprinting, it's only 1 bit. Someone intentionally trying to add fingerprinting could do much more malicious things. Unique font names or uniquely generated font w varying letter widths could completely de-anonymize a user. This seems scoped to identifying team-viewer users, not identifying/fingerprinting individuals.
