If i use setting "Length for blogs activity content" by character and add first a image and after image my text in Write Blog Editor, then i see only the image in JS Activity Stream but no text.

1. Add Image via Media Manager into Write Blog Editor
2. Add Text after Image
3. puplish entry
4. only image is visible in Stream but no text

works perfect:

2. Add Image via Media Manager after Text
3. puplish entry
