Extraneous colors in Gleam type highlighting

[facundoolano]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

When highlighting Gleam code, the type names between parenthesis and in function returns have their first letter with a different font color an background. I would expect those names to either have the same color as the type declarations without parentheses, or to not be colored.

To Reproduce

Example in chroma playground

To reproduce it in the command line:

chroma -l gleam --html <source>

Where source is:

pub type Table = Subject(Message)

pub type Message {
  RegisterFeed(String, Poller)
}

pub fn start() -> Table {
  todo
}
