The bug

When switching between a Mojang account and a Microsoft account, or when switching between two Mojang accounts, the account shown on the Accounts tab does not update. It still displays the previous account used. This only updates after closing and reopening the Launcher.

How to reproduce

1. Sign into a Mojang account in the Launcher
2. Navigate to Settings -> Accounts and click either 'Add Mojang account' or 'Add Microsoft account'
3. Sign in
   Notice how when taken back to the launcher window, the previous account is still shown as 'Active'
4. Close and reopen the Launcher, and navigate to the Accounts tab again
   Notice how the correct account is now shown
