ezsystems/ezpublish-kernel : 6.9.1

Hello,

Problem 1 :
When I add an image in the WYSIWYG I have a JS error in Firefox :
this._getWidget(...) is null

This is in this part of code :
React.createElement("select",

{ defaultValue: this._getWidget().getConfig('size'), onChange: this._updateImage, tabIndex: this.props.tabIndex}

,
this._getImageVariationOptions()
)

But the image is well integrated in the WYSIWYG.

Problem 2 :
1. After, select the image in the WYSIWYG
2. Add a link
3. Click "Save"
4. I have this error JS and no link over the image :
"link is null"

Best regards,
Alexandre
