Commits full sync degrades to the headers full sync

Describe the bug
After processing some amount of headers+commits
messages (several thousands or alike in my current scenario), commits exchange fade out, and node fallbacks to the headers full sync. After new peer connected, node initializes new commits+headers exchange round but it seems that both syncs work in parallel (commits have priority within the peer btw).
To Reproduce
- Launch unit-e in testnet.
- See logs. Grep hints:
headers+commits
,commits full sync asked
.
Expected behavior
During full sync, only headers+commits
must transfer headers.
The normal behavior:
