Description: pan.baidu.com - When playing a video, pressing the space bar will trigger full screen and pause at the same time.
Steps to Reproduce:
When playing HTML5 video normally, pressing the space will pause and not enter or exit the full screen.
The video in the Baidu network disk will trigger both operations at the same time. But to reproduce this problem, you need to enter the full screen state first.
