[ICE: 12] UI crash when bumping fees

[TommyR8]

Describe the bug
When trying to bump a transaction stuck in LowRelayerFee, as soon as the user clicks apply, the UI crashes and shows the error:
Application error: a client-side exception has occurred (see the browser console for more information)
Sometimes it still prompts the transaction confirmation to the wallet correctly despite the error.
