Image aspect ratio test is too strict?

FAQ

• Yes, my issue is not about variability or throttling.
• Yes, my issue is not about a specific accessibility audit (file with axe-core instead).

What happened?

Testing the above URL it says the product image ratios are incorrect:

Original: 63 x 256 (0.25)
Shown: 32 x 128 (0.25)

Its impossible to scale the original image correctly since the original width is 63 pixel which is not dividable without fractional part.

The image aspect ratio should be aware of this. If the rounded aspect ratio with 2 fractional digits of original and shown image are equal it should be measured equal and correct.

The original aspect ratio in this example is: 0.24609 rounded to 0.25

What did you expect?

The aspect ratios of 0.25 are identical so the test result is not correct.
