Bold variant of Helvetica font not found

Description

When using a copy of Helvetica LT Std, the bold variant is not found even though other applications have no problems. I read in another issue that the output of variant-inspect could be useful for tracking down ttf-parsing issues (this is an otf file, but still seems to work) so here's that.

Normal font

Bold font

When using it in typst, it just doesn't work.

Normal Helvetica \
#text(font: "Helvetica LT Std", fallback: false, weight: "bold", [BOLD TEXT])

Output

typst fonts --variants just gives ... no variants for any of the adobe Helveticas (?)
EDIT: grepping only the font family name only returns the line with the font family name 🤦

typst fonts --variant finds them?

fc-list finds them and categorizes their variants correctly

Operating system

Linux

Typst version

• I am using the latest version of Typst

Start by reproducing the Helvetica LT Std case from the issue and compare Typst's variant-inspect and typst fonts --variant results with fc-list. Trace how the font's bold variant is detected and selected; done means the provided Typst example selects the bold font while preserving normal Helvetica behavior.
