Bug description

Fade effect does not work correctly with virtual slides. Several problems:

1. Open link and try to go next slide a couple of times. You will see following:

• First click on next slide button (slide occurs with transition effect)
• Second click on next slide button (slide occurs immediately without transition and after that transition occurs for next slide)

2. In case swiper has "loop" flag, second slide does not shown at all (white screen). To reproduce you need to go click next slide button until slide is not visible (on the second circle you will see that slide 2 is empty)

I have a similar issue - the fade effect technically works with the virtual slides by having imported the import 'swiper/css/effect-fade' CSS when you go from one slide to another in their normal order.

However, I have a slider bullet-based navigation that can scroll the slider to a slide outside the number of preloaded virtual slides, which in turn causes a jump in the animation rather than a smooth fade-in-out.

It would be great if newly added/updated virtual slides would fade in as well.
