请问用selenium模拟点击网络视频的二倍速按钮没反应是为啥？

Question

#定位倍速按钮
speed_control = WebDriverWait(driver, 10, 0.5).until(lambda x:driver.find_element_by_xpath('/html/body/div[4]/div[2]/div[2]/div[3]/div/div[2]/div/div/section[2]/div[1]/div/div[2]/div/xt-wrap/xt-controls/xt-inner/xt-speedbutton/xt-speedvalue'))
#悬浮
ActionChains(driver).move_to_element(speed_control).perform()
#定位二倍速
speed_two = WebDriverWait(driver, 10, 0.5).until(lambda x:driver.find_element_by_xpath('/html/body/div[4]/div[2]/div[2]/div[3]/div/div[2]/div/div/section[2]/div[1]/div/div[2]/div/xt-wrap/xt-controls/xt-inner/xt-speedbutton/xt-speedlist/ul/li[1]'))
#点击
speed_two.click()
