[jenny-s51]

Certification

• I certify I am an Epic Owner for Kubeflow Notebooks 2.0 and expected to create planning-related issues.

Description

While implementing the fixes for #684 a related issue was surfaced by these changes and has been identified via #696. This is a follow-up ticket to address it outside of the scope of #684 - I plan to pick this up after #696 is merged.

Acceptance Criteria

• "Home Directory" label should be aligned with the upper border of the text area
