It seems pretty weird that above text is not italic.
The default font in math is New Computer Modern Math (NCMM). For italic text to work you’d have to have a font NCMM italic installed, but I don’t think it exists - there is no such italic font in the NCMM release what I can see.
The way to do it here would be to define a function to be used for text inside math and use a text font (not math font), a font which has an italic variant, and then it will work well.
#let mtext(body) = {
set text(font: "Libertinus Serif")
body
}
$
s + t quad #mtext[_statiblity_]

Another way is to use covers.
#show math.equation: set text(font: (
(name: "Libertinus Serif", covers: regex("\p{Latin}")),
"New Computer Modern Math",
))
$ s + t quad #[_statiblity_] $

That’s nice to know, and I think typst should move towards an official solution to this problem[1]. It’s already gotten a lot better with Typst 0.14, to be sure.
I wish it was as easy as using covers, but the drawback I’d point out is this case:
#let mtext(body) = {
set text(font: "Libertinus Serif")
body
}
$ s + t quad #mtext[_this_ & more] $
With the covers solution the ampersand would still use the math font. Is there a way without a function like mtext - I think - to have symbols correctly using math vs text font in their respective contexts?

I believe the answer is no. covers does not even distinguish between { in texts and cases.
Looking closer at issue #366, I’m not sure why box has not been mentioned in the workarounds there. Box resolves the problem of nested equations (but some problems remain):
#let mtext(body) = box({
set text(font: "Libertinus Serif")
body
})
$ X = {1, 2, 3} union {#mtext[multiples of $3 + p$ where $p$ is a prime]} $
$ Y = T^#mtext[index $script(pi)$] $ // no automatic script size here

I’m glad to see a workaround while a official solution would be better.
But it seems a tricky problem to choose which font in edge cases.
