On mobile devices, when changing orientation, or if the player gets resized, the captions won't update to reflect the new orientation or player size. However, they do get updated the next time they are redrawn. Instead, we should redraw the captions whenever `orientationchange` and `playerresize` get triggered.
It's possible that ResizeManager will trigger its debounce handler but
then get disposed before the handler runs. This can cause tests to fail,
so, instead, we should cancel the debounce when ResizeManager is
disposed.
If Promise is available or if Promise is polyfilled, then we'll return a new Promise from `play()` that will get fulfilled with the value returned from the `play()` method. This means that on IE11, this promise will get resolved when we call `play()` even if play doesn't succeed. We will have a follow-on PR to polyfill this behavior and resolve or reject the promise for browsers like IE11 that don't return a promise from `play()`.
Because we add Touch Activity in the parent class and those don't actually get removed in Resize Manager we leak on every dispose. Calling super.dispose() cleans them up because we remove our list of handlers via a call to DomData.removeData

It's possible for us to get a blob url for sourceset, but when we do, we
shouldn't update the source caches with that information.
blob urls can arise when playback is done via Media Source Extension (MSE) such as m3u8 sources with @videojs/http-streaming (VHS).
Angular CLI, and potentially other projects, may use the "pure_getters" compression option of uglify which will end up removing the getter line we use for side-effects to update the active cues. This update makes sure that the line doesn't get removed.

Trigger the change event on the next tick. This means that multiple changes to a track's mode will only result in a single change event on its associated TextTrackList rather than 3 events as it may be currently.
Fixes#5159
setSource is useful if you care to be fiddling with the source or doing some work depending on what source is set. However, sometimes, you don't need a setSource and want the middleware to always be selected.
Now, if setSource is missing, it will implicitly be included in the middleware chain.
