Prompt window remains open despite wallet timeout lockout triggering #250
Description
Describe the bug
If my wallet locks due to timing out from inactivity, any prompts which were active at the time will remain open despite the underlying wallet having locked.
To Reproduce
Unlock your Beet wallet, create a prompt, go inactive for several minutes in order for the wallet timeout lock to trigger, navigate to still open prompt with a locked wallet.
Expected behavior
If a wallet is locked, the prompt window closes.
Additional context
Note: Attempts to approve prompts will fail whilst the wallet is locked, and new prompts will not trigger whilst locked.
Alternatively, since broadcasting whilst locked is impossible then it's not a security concern, we could allow the user to build up dozens of 15k op TRX over several hours & multiple wallet timeouts, then when prepared properly they can approve multiple in short succession..
