Truncated text when using style on a subgraph title

[Jacques-Olivier-Farcy]

Setup and configuration

• Mermaid version: 3.1.10
• MediaWiki version: 1.39
• PHP version: 7.4
• Database system (MySQL, PostgresQL, etc.) and version: Mariadb 10.5

Issue

Produces a stack trace and outputs:

When applying a style to a subtitle, when text size is increased, it is truncated :

{{#mermaid:graph LR;
 subgraph styleTitle [Support tickets]
  BLOC1[[Test]] --> BLOC2(Test bloc 2)
end
%% Style of title
    classDef Title fill:#FF99FF00, stroke-width:0, color:grey, font-weight:bold, font-size: 15px;
%% style
    class styleTitle Title;
}}

All is workgin good:

But when i change the size of the text:

{{#mermaid:graph LR;
 subgraph styleTitle [Support tickets]
  BLOC1[[Test]] --> BLOC2(Test bloc 2)
end
%% Style of title
    classDef Title fill:#FF99FF00, stroke-width:0, color:grey, font-weight:bold, font-size: 25px;
%% style
    class styleTitle Title;
}}
