Gantt Diagram stopped rendering after 15th activity

[skye0402]

Describe the bug
A Gantt chart is not rendered in Mermaid Live and CLI - however, no error is raised either.

To Reproduce
Steps to reproduce the behavior:

1. Go to Mermaid Live editor (but same problem with CLI) in latest version: https://mermaid.live/edit
2. Paste in following chart:

3. No diagram is rendered, no error is thrown.
4. Remove the last line ("Interactive Session") - Gantt Chart is rendered as expected.

Expected behavior
A Gantt chart should be rendered for the code provided. Alternatively an error should be thrown (but I believe it's syntactically correct).

Screenshots
Just test it on the https://mermaid.live/edit
