tabindex for slides about splide

Now you can determine whether to add tabindex to slides or not by the slideFocus option. Set it false and all tab indices will not be inserted.

You suggest removing tabindex from all slides, right? I'm not sure what is the best solution about a11y for a slider including tabindex because there are many different suggestions. Here are interesting issues of other sliders:

• kenwheeler/slick#2338
• ganlanyuan/tiny-slider#4

Also, we should aware of the keyboard navigation such as "right arrow" for going to a next slide. To receive keydown event, a slider must have a focused element. If a slide doesn't have tabindex=0, only arrows and dots are focusable but they are not always displayed, depending on options. Some slider plugins set tabindex="0" to its container element but it is not an user-actioned element, isn't it?

I will keep researching this.

Hi! I'm creating a slider with <a> tags using react-splide and came across some issues understanding slideFocus:
1 - Does it controls both the tabindex on the visible splide__slides and the negative value on focusable elements?
2 - Do the focusable elements need to be direct children of the splide__slide to receive the tabindex=-1

I'm having an issue where I want the tabindex=-1 control on <a> tags outside the view, but I don't want the tabindex=0 on visible splide__slides, since my slides already have focusable elements. Is there a way to achieve this behaviour?
