Pointer input stops working after app returns from background (Capacitor integration)

[lheido]

Hi everyone 👋

I'm integrating Excalibur.js into a Capacitor mobile app, and I've run into a tricky issue with pointer input.

When the app first launches, everything works great — I can capture input via engine.input.pointers.primary.on('down', ...) without any problem.

But... once the app goes into the background and then comes back to the foreground, pointer input completely stops working. No down, up, or move events are triggered anymore.

Here's what I’ve tried:

• Listening to Capacitor's appStateChange to detect when the app resumes
• Manually re-registering pointer event handlers after resume

Unfortunately, none of these have helped.
Thanks in advance for any help or guidance — and thanks for the great work on Excalibur! 😄
