We have noticed Watson is adding non-breaking spaces ( ) inside empty table cells which potentially cause HTML layouts to get broken or not parsed properly.

A support case has been opened in order to swithc this funtionality off for our organization but then not only it stopped from adding non breaking spaces but also started to remove them when present, forcing us to roll back to the previous situation, meaning we are now getting back non-breaking spaces being inserted automatically every time an empty cell is found on the HTML template.

Ideally we would suggest Watson not making any changes over HTML coding since any unwanted piece of code being removed/added may result eventually in layout being affected unexpectedly.
