Italic text has inconsistent weight in some fonts

[ssotoen]

Description

I tested this with the Reforma superfamily (Reforma 1918, Reforma 1969, Reforma 2018) but the issue might exist for other families with similar weights as well.

The Reforma families each have 3 weights, with the lightest one (“Blanca”) being the default, “regular” weight. However, when the font weight is set to regular, italicised text is displayed with the medium weight (“Gris”).

This issue is exclusive to the web app; I can’t reproduce it locally.

Code

#set text(
  font: "Reforma 1918",
  weight: "regular",
)

#let it = text.with(style: "italic")

This is _emphasised_.

This is #it[italicised].

#set text(weight: "light")

This is _emphasised_ and #it[italicised] with light weight.
