## Description

When creating a slider with minimumValue = -10 and maximumValue = 0, the application in android works as expected, but on iOS the maximumValue gets overwritten to 1.

## Reproducible Demo

```
{console.log('CURENTLY AT: ', value)}}
onSlidingComplete=={(value) => {console.log('COMPLETE AT: ', value)}}
tapToSeek={false}
/>
```

Using this slider the logs will show `CURRENTLY AT 1` when sliding fully to the right on iOS and 0 on Android

## My current workaround
I set maximum to 0.1 and for my business logic in `onSlidingComplete` I do `Math.min(value, 0)`

Start by reproducing the reported slider configuration on iOS and compare it with Android. Trace the iOS Slider implementation for how minimumValue and maximumValue are handled when maximumValue is 0, then add or update coverage for the negative-minimum, zero-maximum case. Done means the slider reaches 0 on iOS without changing the supplied maximum value.
