When using the RD&D Composer, Hero or Image building blocks and changing the image the insterted image is getting out of proportion.
Example:
This is the HTML from the as-is template as soon as you create a newsletter based upon the D&D Composer
<img src="https://unsplash.it/500/300?image=885" alt="Insert alt text here" style="max-width: 100%!important; width: 500px!important; height: auto!important; display: block; color: #666666; font-family: Helvetica, arial, sans-serif; font-size: 16px;" class="img-max" border="0" width="500">
So, I guees the source image (https://unsplash.it/500/300?image=885) is 500px – indeed it is – 500 × 300 pixels.
Next, I change to an image I want to use that is 197 × 256px and look at the HTML I see this –
<img src="http://path/wp-content/uploads/Image.png" alt="Insert alt text here" style="max-width: 100%!important; width: 500px!important; height: auto!important; display: block; color: #666666; font-family: Helvetica, arial, sans-serif; font-size: 16px;" class="img-max" border="0" width="500">
Surely a bug as it’s keeping the 500px width attribute.
