Describe the bug

When I use something like {% picture path.jpg class="right w-50" %} the refactoring code lifts the w-50 class to the enclosing , which is as intended. When I introduced some class definitions of my own, which were called w-50vw, they were lifted to the as well.

The code in the refactoring checks only for class names starting with "-w" and then lifts the whole thing. Originally meant for the bootstrap classes w-25, w-50, w-75 and w-100, perhaps they should more specifically check for those, but leave things like w-50vw alone so they will be applied to the img tag.

Furthermore, I defined some more classes, such as w-30, w-35 etc. to expand on the bootstrap set. In this case, of course, I would still want them "lifted" so perhaps the best check would be w-, or just simple document more clearly that any class prefixed with "w-" will be lifted. I could live with either one.

Steps To Reproduce

1. Use "{% picture path.jpg class="right w-50" %}" and observe the w-50 class placed on the refactored around the img.
2. Use "{% picture path.jpg class="right w_50" %}" and observe the w_50 class placed on the img
3. Use "{% picture path.jpg class="right w-50vw" %}" and observe the w-50 class placed on the refactored around the img.

Expected Behavior

Expectation is to either:

• Document any classes with prefix "w-" will get "lifted", and/or
• Only lift classes of the form "w-" and document

This will allow anybody writing their own classes starting with w- not to be bewildered why they don't appear on the img tag.
