Magikeyboard: Select from the group that the previous entry was selected from

### Checks

- [x] I have read the Wiki, searched the open issues, and still think this is a new feature.

### Explain the problem clearly and succinctly:

Whenever I try to log into Github from a different IP it sends an OTP to my email.

I have the Github, and email entry in the same group.

### Describe the solution you'd like:

It would be great if I could open and use the Github entry and after clicking on the *Key* icon it would automatically open up in that group so that I could select the email.

### Describe alternatives you've considered:

_No response_

### Additional context:

#1185 seems related to this. I was initially make this a comment on that issue, but this is seems slightly different to me and is about Magikeyboard, so I created a seperate issue.

Start by tracing the Magikeyboard flow from the Key icon on the Github entry, using the related #1185 issue for context. Verify how the previously selected entry and its group are tracked; done means opening the key action lets the user select the email entry from that same group.
