there is no spare time to debug this issue because of the workload of protobiochemistry. I decide put it into version 3.6.1. Hope to understand.

These two part label segment are all 50.4 height(1.26*lineHeight). it is designed to avoid border truncation. It is hard to remove the hack modification. It will be resolve when richtext is restructured.
