+## Video tag doesn't fire "ended" event
+
+When using a video tag, the "ended" event is not fired when the video is finished playing. This is a bug 
+in WebkitGTK, however you can use the following workaround to fix it:
+
+```js
+videoTag.addEventListener("timeupdate", (event) => {
+    if(event.target.duration - event.target.currentTime < 0.2) {
+        let ended = new Event("ended");
+        event.target.dispatchEvent(ended);
+    }
+})
+```
