Bug description

After stopping autoplay, waiting for a number of seconds longer than the delay time, then starting autoplay, the timeLeft and percentage values in the autoplayTimeLeft event are negative.

Expected Behavior

The timeLeft and percentage should accurately reflect the time left before transition to the next slide and percentage of that time related to autoplay delay.

Actual Behavior

Using the reproduction link, run swiper.autoplay.stop(), wait for 5-10 seconds, then run swiper.autoplay.start().

The autoplayTimeLeft event will get negative numbers for timeLeft and percentage, and the progress countdown UI element will reflect this.

Swiper version
