"New login" popup validation button not doing anything

### Steps to reproduce

1. Connect a new client
2. Element desktop pops the pop-up you'll see in the below screenshot asking if it was me
3. I try to click "Yes, it was me", but it does absolutely nothing and the popup stays here.

### Outcome

#### What did you expect?

It should validate the device

#### What happened instead?

It did nothing

Additional information:

- Maybe the client cross-checking with emojis (initiated by the connection on a new client) bypassed it and considered it as validated, therefore this pop-up fails to do what it's supposed to do as it's already done (don't know)
- I didn't tried the "No" button as I don't want to invalidate that device, so I can't tell if that one would work or no.

### Operating system

Arch Linux

### Application version

1.11.50-1

### How did you install the app?

Package manager

### Homeserver

_No response_

### Will you send logs?

No

No file, test, or entry point is named. Start by reproducing the new-client login popup on Element desktop with version 1.11.50-1 and inspect the validation flow, including whether emoji cross-checking changes its state; done means the “Yes, it was me” action validates the device and dismisses the popup.
