No, 6.4 did not fix this problem. Why is CE inserting span tags into the editable text? I am fetching the field content into the .Text property directly from our CMS database, and the span tags are NOT in the database.
// In my class which subclasses CE. This is a database get.
Text = GG.GetWebPageFieldContent(pageName, pageSubName, Id);
Here's the actual field on the database. The spans are not there.
Here the same field in the CE editor.
