I can't interact with the timeline of the video

[x] bug report
[ ] feature request

Hello,
the slider works correctly, but if I want to add a video inside the slide, I cannot interact with the timeline of the video, and if I try to move the pin of the progress bar, the touch is taken by the slide and the slide starts to move (as if I wanted to change slides).
This strange behaviour only happens on iOS (simulator and real device - iPad) and i can't figure out why.

Expected behavior:
I would expect that I could place the video time slider where I want within the timeline.

Steps to reproduce:
Put a video inside a slide

<ion-grid>
    <ion-row>
        <ion-slides>
            <ion-slide video-slide *ngFor="let item of videos">
                    <ion-item class="outerIonItem">
                        <div class="favImgDiv">
                            <div class="videoDiv">
                                <video *ngIf="isIosDevice" preload="metadata" controls muted playsinline>
                                    <source src="{{item.localPath}}" type="video/mp4">
                                </video>
                            </div>
                        </div>
                    </ion-item>
                </ion-slide>
        </ion-slides>
     </ion-row>
</ion-grid>
