Word Bug prevents formatting of paragraph

When you add chemistry into a paragraph the Add-In protects its contents by locking the Content Control which is inserted.

A bug exists in Microsoft Word (present in versions 2010, 2013 & 2016) which prevents adujsting of a paragrah’s formattting (such as centering etc) when the first “character” is a locked Content Control. This also applies to table cells and has been reported to the Miscosoft Office Team.

To get around this add a space before inserting a Chemistry object.
