mo.ui.slider with very small step value does not work

[vangberg]

Describe the bug

If I create a slider with a step value of 10**-7 the slider does not respond. A step value of 10**-06 works fine.

This is coming from an upstream library and looking through their code, its likely a rounding issue.

The seemed to fix this for small numbers, but I am guessing not this small. https://github.com/radix-ui/primitives/issues/462 https://github.com/radix-ui/primitives/pull/463

we may have better luck switching to react-aria-components

I am using

dependencies = [
    "marimo>=0.14.12",
]

still cannot use the slider, even though the PR has already merged. Would you like me to explore the React ARIA slide? @mscolnick ?

@rubiagatra, yes if you are open to exploring migrating ot react-aria-components, that would be really appreciated.

it would be good first to check if they support this small of a step, before doing doing the full migration
