There is some odd behavior especially inside a editable containing
newlines.
For example in the sale description on an ecommerce item, lines could
contain newline (it is editable from backend) but as an effect of other
use case, pressing enter could have a range of unwanted side effects:
- removing all the content,
- duplicating the editable (should never happen, if we have one field
"description_sale" we don't want to duplicate it, this has no sense)
In a product name which is in the same use case, there is no newline so
the problem is not apparent, and ENTER do nothing. This is the behavior
we should want in every instance.
If we still want a newline, we have to force it with SHIFT + ENTER key,
also this is regarding field that may or could be present in the backend
views, so it could also be edited in backend.
This change make ENTER ignored when we are editing a node directly child
of an node being edited.
A second part of the issue was that dom.removeBetween (used to remove
content inside a range) could remove the ancestor node that was an
editable. This is not wanted.
For example if we did CTRL + A inside a field with `<br />` then ENTER
or pasting something, the field would be removed and not just emptied
and could not be gotten back without editing the template manually.
This was sometimes mitigated because if a `<br />` was at the end of an
element, it would stay in this use case avoiding the issue.
