Changed

• Bump probe-image-size module to v7.2.2 [#6036]

Fixed

• Fix mapbox derived coordinate for Retina displays [#6039]
• Fix interaction between uirevision and autorange. Because we push autorange and range back into layout,
  there can be times it looks like we're applying GUI-driven changes on top of explicit autorange and other times
  it's an implicit autorange, even though the user's intent was always implicit. This fix treats them as equivalent. [#6046]
