[react] fix: Improve the inspect view (#323)

Improve visuals of the Xray path component

- Return null for hidden paths in the Path component. This fixes #266 and restores v3 behavior here. (An optional toggle to show hidden paths might be useful in the future.)
- Reverse animation direction in stroke-dashoffset. This ensures that the path animates in the internal direction, which is less confusing since you can hover over a path to check that it is counter-clockwise.

Also remove a duplicate array key.
