POS: When using barcode scanners, ticket information might not get properly shown before enter prompt

[akx]

Something has changed in modern Chromes that causes the prompt() for committing a ticket usage to be shown before the UI in the background has a chance to update to show the ticket information.

This only manifests when using sufficiently fast input devices such as barcode scanners, or for debugging the issue, an AutoHotkey script like CapsLock & C::Send 123123{Return}.

@japsu has hotfixed this in Kompassi by using setTimeout: con2/kompassi@282d0ca#diff-edd209dab48c8dc758347b39388c940cR127

Might be worth it to look into changing the prompt into something less intrusive, such as a DIY HTML prompt.
