invalid transient state during staking #2234
Description
In staking, when delegating an amount of rose, for a while a pending screen is shown. Then the screen is hidden, but the form is not reset immediately, but after a short while (1 sec or so).
This transient state doesn't make sense, because if the process has finished, the form should be reset; and if the process is still pending, then it was too early to hide the pending screen.
