I'm exploring a potential fix for the checkpoint text wrapping issue when using non-English languages. I'll investigate the CSS styling and text rendering behavior for checkpoints across different locales.

I've opened PR #8207 with a fix for the checkpoint text wrapping issue: #8207

The fix adds a whitespace-nowrap CSS class to prevent the checkpoint text from wrapping when using non-English languages with longer translations.

Note: There's currently one failing integration test in the CI, but it appears to be unrelated to this change (the fix only adds a CSS class). The other checks including unit tests, compilation, and code quality checks have all passed.

The UI element for the checkpoint is overly intrusive, creating a significant visual distraction for the user.
