Description: 

Responsive image styles image_style_mappings should be numerically ordered by the multiplier with the lowest multipliers first. To manually repair the issue, review all responsive_image.styles.* image styles for the correct order of image_style_mappings. All image_style_mappings should be ordered by the multiplier.

Previously

The order for the multiplier would put floating point multipliers in the wrong order:

  1. 1.5x
  2. 1x
  3. 2x

After

The fixed order is:

  1. 1x
  2. 1.5x
  3. 2x
