*:last: and last:*: shouldn't be the same

UnoCSS version

66.5.12

Describe the bug

It looks like the order of combining multiple variants is not always respected. My repro tries *:last:_ and last:*:_ and both results in the same selector and the same visual output.

I expect the first to generate _ > *:last-child and the second _:last-child > *.

This is incompatible with Tailwind, which applies those as I describe. I provide a Tailwind playground for comparison.

Related? Issue #4962 looks similar, although the syntax used to target children is different and according to comments that bug was fixed.

Reproduction

Here's a UnoCSS playground.

Note that red and green cells are the same, although they shouldn't. Please check Tailwind Playground above to see the visually correct result.
