Inline Variants - shape=rect being added


I have a really simple inline variant, just a styled div, with a basic <a href=""> tag. I’m using Rx 6.6

When it is rendered, the a tag has the mysterious addition of attribute shape=“rect”. This gets picked up in validation checks and is causing me woe.

In the bad old days, inline variants and links etc were passed through an XSLT, I think sys_variants.xsl, but even if this is still the case, this doesn’t seem to explain what is happening here.

Any great thoughts?
