Difficulty selecting the lowest value in the range widget

[garethbowen]

Expected Behaviour

It should be easy to click on whichever value you want.

Observed Behaviour

You have to be very accurate when clicking at the low end of the slider or it doesn't change.

Reproduction Steps

Additional Context

The workaround is to drag the slider handle all the way to the start which works reliably.

I think the proper fix for this requires changing the algorithm in the primevue widget, around here: https://github.com/primefaces/primevue/blob/16f6c223bb926743bed5f4330f55e9765f031f2f/packages/primevue/src/slider/Slider.vue#L122

Instead of Math.ceil it should find the closest step.

What do you think about trying a quick issue then PR to PrimeVue? I've observed that for things that are well-described they're usually pretty quick to take in improvements. For some reason they tend to do direct commits instead of merging the PRs but I think they do look at the suggested approach. Sometimes they do merge directly as well.

It's tempting. There's this issue, and others (particularly #750 and #713, but also #777) which would be good to get patched if they're responsive. But to be honest I haven't been very impressed by other bugs/PRs not getting looked at, and constant regressions. At the moment we can't even upgrade so even if these did get merged and released we might have to fix other blockers to upgrade and resolve.

Let's talk about it - maybe I'm just too cynical.
