Bug description

When the buttons for moving the slides back and forth are inside the slider and the user clicks on the button for moving to next or previous slide, the slide is moving to next or previous slide accordingly. But after the slide is changed, if the user switches browser tab / browser window and coming back to the tab/window containing swiper, the slider is moving back to previous slide from where the button is clicked.

Steps to reproduce:

1. Click on 'Next' button in Slide 1. The slider will go to Slide 2.
2. Do a tab switch / window switch and come back to the swiper tab.
3. Observe the slide number. It is coming back to Slide 1 from where the button is clicked.
4. Similarly, click on 'Next' button in Slide 1.
5. In Slide 2, click on 'Previous' button. It will go to Slide 1.
6. Do a tab switch / window switch and observe the slide number.
7. It should be on Slide 1, but it is moving to Slide 2 from where the button is clicked.

Expected Behavior

The slider should stay in the same slide instead of moving to previous slide on tab/window switch.

Actual Behavior

The slider is moving to previous slide instead of staying in the same slide on tab/window switch.
