Bug with jetpack ?

Hi,

(sorry for my english :p)

My amp posts are ok for google but some amp posts display their image with fixed width (exemple : https://www.paysan-breton.fr/amp/2017/02/les-salons-de-lagriculture-choc-de-civilisations/

Bug with captions >

Jetpack force the image width with “?resize=450%2C300” parameter.

Can you fix it ?
