Video controls like pause/resume are not working when voiceover is on in IOS .

When voiceover is turned on in IOS devices the video controls like pause/resume, forward , backward are not working in inline mode and works fine in fullscreen. The controls are announced properly in voiceover,but when we press it, it is not performing any action at all. We used HTML5 video tag to display mp4 video in our app.we have added all necessary accessibility tags as well. We also observe the same issue is happening in the w3school web page. Attaching the link here for reference. (https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_video) Could you please guide us why the video controls are not working. Is there anything we want to change or any update needed from the safari side.
