Bug in transform for amp

Hello,

When we use a balise ““, the transformation was incorrect.

for example:

in

<a &nbsp;onclick="trackOutboundLink('https://twitter.com/JAF_Emploi'); return false;" href="https://twitter.com/JAF_Emploi" target="_blank">

become :

<a target="_blank" href="https://twitter.com/JAF_Emploi" return="" false="">

have you got an idea how to resolve this ?
