VideoPress: Videos not playing in Instagram in-app browser on Android

A user reported, and I was able to replicate, that VideoPress videos embedded on their WordPress site do not play when the site is opened in the Instagram in-app browser on Android devices. However, the same videos play correctly in the Instagram in-app browser on iOS and in external browsers like Chrome.

If the user chooses the option to "Open in Chrome" (or another external browser) via the three-dot menu in the Instagram browser, the video plays correctly.

Steps to Reproduce:

1. Embed a VideoPress video on a WordPress site (tested using Elementor).
2. Share a link to the site in an Instagram Reel or Post.
3. Open the link via the Instagram in-app browser on an Android device.
4. Note that the video will not play

The expectation is that the video should play within the Instagram in-app browser on Android, similar to how it does on iOS. Here's how it works on iOS:

Tested on:

- Android (Instagram in-app browser): Issue present
- iOS (Instagram in-app browser): Video works as expected
- Chrome (Android and iOS): Video works as expected

@Automattic/nexus Would this be something you could investigate?

Start by reproducing the VideoPress playback failure from an embedded WordPress site opened in Instagram’s Android in-app browser, then compare it with Instagram on iOS and Chrome. No files or tests are named; done means the embedded video plays in the Android in-app browser without regressing playback in the working environments.
