Huge Gap Is showing before and after the rendered of sequence diagram

[MayurMundekar]

Describe the bug
We are migrating from 8.2.6 to 8.12.0 one of our existing diagram is not rendering properly in 8.12.0. In mermaid 8.2.6 one of our sequence diagram is rendering properly but in 8.12.0 there is huge gap before and after the sequence diagram. We verified in mermaid live editor and there also it is giving same issue.

Expected behavior
There should not be gap before and after the sequence diagram
