What?

  • Our lazy loading solution relies on advance knowledge of the image dimensions. When logo_size is set to original in the theme settings, we don't have this information. For large logos, this leads to overlapping of the menu.
  • For original sized images, don't use lazy loading or reserving space for the image via absolute positioning. Hopefully not many users will use this setting because it will impact frontend performance. To partially mitigate this, I reordered the options for logo_size so our optimized setting appears first in the list.
  • The large diff in schema.json is due to changing the line endings from dos to unix. The only change of substance is reordering the options for logo_size

* Our lazy loading solution relies on advance knowledge of the image
  dimensions. When `logo_size` is set to `original` in the theme
  settings, we don't have this information. For large logos, this
  leads to overlapping of the menu.
* For original sized images, don't use lazy loading or reserving
  space for the image via absolute positioning. Hopefully not many
  users will use this setting because it will impact frontend performance.
  In order to hopefully minimize this, I reordered the options for
  logo_size so our optimized setting appears first in the list.
