Error with image caption

[JCauz]

Hello,

We are experiencing issues with some images that include captions. A javascript error occurs due to a space between the img tag and the span tag of the caption. The problem comes from the fact that it tries to do a nextSibling to get the span tag of the caption but gets the space instead which suddenly crashes the javascript when it tries to do a setAttribution on the element.

Would it be possible to do a fix to correct the problem?

Thanking you
