math.class is not taken into account within a context expression

[loutr]

Description

I maintain the tiny xarrow package and the latest version 0.11 of the compiler seems to have brought a regression, which impacts the package. A minimal example is the following:

#let test = math.class("relation", "--")
$ a test b $

displays correctly, with an appropriate spacing around --, but

#let test = style(_ => math.class("relation", "--"))
// or the new #let test = context math.class("relation", "--")
$ a test b $

doesn't (it has an extra space between -- and b).

This is easily fixable in the case of xarrow for instance, where it boils down to swapping operations as in:

// where expr depends on context of course
#let test = math.class("relation", context expr)

but I figured it would be best to signal it anyway. Sorry if this is a duplicate or my mistake or anything. Thanks for your amazing work as always!

This seems like it might be related to the issue with the math-call-pass-to-box test I added? See here: #3786 (comment) If so, it would be fixed by whatever happens with #1125 and #1779 .
