Rotating screen loses state on webview screens

[diareuse]

Current behavior

When paying, I inadvertently turn my phone, and I'm back at ticket selection. Only the places selected by me are blocked for 10 minutes, right?

Expected behavior

Rotating a device screen shouldn't make it lose state at any point.

Replication scenario

Steps to reproduce the behavior:

1. Go to cinema or movie detail
2. Click on any time
3. Complete the purchase flow to a point where you should pick seats
4. Rotate screen
