mini preset: Custom CSS Variable generation changed in v0.49.1

[samydoesit]

Hello some of our tests are failing because some custom variables are wrong generated as "--v" instead of some other name.

shortcuts: [
   ['testString', `selector-[.test]:([--min-width:20px] [--col-gap:20px] [--content-min-width:calc(var(--min-width)_-_2_*_var(--col-gap))])`]
],

--- .test{--min-width:20px;--col-gap:20px;--content-min-width:calc(var(--min-width) - 2 * var(--col-gap));}
+++ .test{--min-width:20px;--col-gap:20px;--content-min-width:calc(var(--min-width) - 2 * var(--v));}

This could be introduced in relation to v.0.49.1 with this change: : #2115

Here is a Sample: UnoCSS Playground

This has worked until 0.49.0. Is there anything wrong how we generate the variables? We could also move this to preflights.

I'm experiencing this issue as well. In my case, a class pb-[calc(var(--cy)+var(--cx))] is generated as:

padding-bottom: calc(var(--cy) + var(--v));

For now I've downgraded back to 0.48.5.
