Previously hover toolbars reqiured a wrapper with the class sc-element and inside it a ...Toolbar, something like this:

<div class="sc-element">
  @Edit.Toolbar(Content)
  ...
</div>

Usually there was a lot more HTML, but this is what caused the toolbar to float. To simplify the new way to do it is as follows:

<div @Edit.TagToolbar(content)>
  ...
</div>

To migrate into this, do this

1. Find all sc-element classes (they marked all floating toolbars)
2. Within that HTML, find all @Edit.Toolbar(...) or something.Toolbar and move it into the tag that has the sc-element, but use @Edit.TagToolbar(...)
3. Remove the sc-element class
4. Test it
