When adding an attribute to a content fragment which also contains data-classid, the attribute's value keeps encoding.
Steps to reproduce:
1. Add block to tiny mce.
2. Inspect block and edit as html, add data-caption="Cat & Dog".
3. Publish the page (Note: data caption is encoded as expected).
4. Repeat steps 2 and 3 (Note: data caption is encoded again, and repeating these steps encodes them over and over).
Data-caption should be "Cat & Dog".
Data-caption is double encoded.
"Cat &amp; Dog"
