New PAT creation corrupts the page

description

When creating a new personal access token (which is successful), I noticed that the page becomes corrupted.

• the button loses its content (it's blank and small)
• the page becomes unusable - can't create a new PAT or otherwise interact with the form
• subsequent tokens cannot be made

to reproduce:

1. Open the inspector in the browser
2. Navigate to the PAT page https://gitlab.com/-/profile/personal_access_tokens
3. Create a token (I ticked api only)
4. Notice the page changes (button loses its content)

5. Try to make another token. The form is unusable.

The network tab and console indicate that this is a frontend issue rather than a backend issue 🤔

env

This occurs on gitlab.com.

workaround

Refreshing the page restores the form so it works again.
