When clicking "connect wallet" on the /stake page, the loading states of the page trigger and the button's label changes to "Stake STT". When closing the connect wallet dialog without connecting a wallet the loading states are still active.
The loading states should stop if no wallet is connected. Imo it would also be best to not show loading states as soon as we open the connect wallet dialog, but only start displaying them when the user initiates the wallet connection (e.g. clicks on Metamask in the screenshot above).
