Timing out of deposit signing causes weird error "can't access property "switch""

[kovipu]

Timing out of deposit signing (atleast with Freighter) causes weird JS error. This could be more descriptive

Is there a way to listen for the user closing that signing dialog / timing out?

To reproduce:

1. Press deposit
2. Enter amount and continue to sign the tx
3. Close the Freighter signing window -> deposit loading spinner still spins
4. Wait for the error to appear
