[Bug] Dialog not closing on back button on Capacitor build

[vycoder]

Describe the bug
QDialog doesn't close when device back button is clicked on Capacitor apps. Cordova works fine as is but for some reason on Capacitor build, nothing happens when device's back button is pressed.

Codepen/jsFiddle/Codesandbox (required)
Any non-persistent QDialog ie: https://codepen.io/yev/pen/dyPqjJp

To Reproduce
Steps to reproduce the behavior:

1. Create a fresh Quasar project
2. Use plain QDialog component
3. Make sure persistent prop is not set
4. Add capacitor mode
5. Build android apk
6. Install, open app and open dialog
7. Click device back button
8. Nothing happens

Expected behavior
The dialog should close same behavior like hitting esc-key.

@pdanpdan it looks like that specific issue is already fixed. I'm not particularly sure why it happens on quasar capacitor build though. Is there any more information that might explain what happens based on the related capacitor issue?

Will do a test (in the next days) to see if the Capacitor API supports this correctly and will update Quasar. We currently allow the auto closing behavior on Cordova only.

This will be available in "quasar" v1.9.3.
