Before this commit, only the immediate parent of a selected node was
checked for HTML content support in order to determine the toolbar's
visibility. This led to incorrectly displaying the toolbar for fields
like the 'list-price' on an e-commerce product page, whose text content
is wrapped in an extra 'span' element inside the field's span element.
This commit fixes it by checking all of the node's ancestors up to the
editable root for the attributes that determine if a field supports HTML
content.
This commit also prevents a server error if the user somehow styles the
product's price (with ctrl+B for example. It's worth noting that such
style would not be kept in the saved version of the page).
lxml.HtmlElement's `text` property has `None` value if the span element
does not contain any text before its first child element
(see https://lxml.de/apidoc/lxml.html.html).
Therefore an element like `<span><strong>42.00</strong></span>` would result
in `None` when reading its `text` property.
The `text_content` method is more suitable for such task as it returns the
text content of an element and its children.
