Equal sign "=" no longer valid in participant of sequence diagrams

[digitalmoksha]

Description

In 11.4, using an = in a participant name of a sequence diagram gives an error. This used to work in 10.7.0.

Steps to reproduce

When using 10.7.0, the graph

sequenceDiagram
   x->>y=true: Transition to true

used to work.

However now with 11.4 (haven't tested any other previous 11.x versions) it gives an error

Error: Error: Parse error on line 2:
...enceDiagram x->>y=true: Transition to
----------------------^
Expecting 'NEWLINE', 'AS', ',', 'SOLID_OPEN_ARROW', 'DOTTED_OPEN_ARROW', 'SOLID_ARROW', 'BIDIRECTIONAL_SOLID_ARROW', 'DOTTED_ARROW', 'BIDIRECTIONAL_DOTTED_ARROW', 'SOLID_CROSS', 'DOTTED_CROSS', 'SOLID_POINT', 'DOTTED_POINT', 'TXT', got 'INVALID'

This seems to be a backwards compatibility bug.
