Proposal

• Address the following finding on the Blame page:
  • Vertically center page buttons between top bar and content
• Additional notes and guidance to resolve this finding:
  • The vertical alignment of this button is off from the other inline content so this icon appears to sit lower than the doc-text icon to the left.
