- Around line 404-415: Update the Tiny_Image test’s first-run setup so the
original lacks conversion metadata while an existing thumbnail includes
convert.type, then add the new size on the second run and assert it inherits the
thumbnail’s format. Ensure the assertions exercise non-original-size metadata
scanning rather than relying on Tiny_Image::ORIGINAL.

Exercise a converted non-original size.
The first run records conversion metadata only for Tiny_Image::ORIGINAL. Tiny_Image::convert_to() can therefore satisfy the second-run AVIF assertion from the original metadata, without proving that it scans non-original sizes.
Arrange the first run so the original has no conversion metadata but a thumbnail has convert.type. Then add another size and assert that it receives the thumbnail format.

Will ensure the mimetype for all sizes are consistent.
background
Encountered a bug where sizes within one image were mixed.
If the client supports avif, webp will never be shown. So therefor we never want to create mixed formats for the same image.
src/class-tiny-image.php:638did not solve this correctly as it was missing a condition inversion!. Though if a different size would be converted earlier, then this would still be mixed. So therefor we will now look for the first image that is converted.Summary by CodeRabbit
