Keyboard controls are inverted on vertical sliders #5
Description
Describe the bug
The keyboard controls are inverted on vertical sliders due to the rotate(90deg) style attribute.
If you change it to -90deg the indicator works as expected but now the slider flips its direction.
To Reproduce
Steps to reproduce the behavior:
- Focus the range input
- Use the arrow keys to navigate the slider
- See error
Expected behavior
The slider needs appropriate keyboard support. Pressing the up arrow key ↑ should move the slider and it's indicator up, the down arrow key ↓ should do the opposite.
