Masayuki Nakano 121e90ba98 Bug 1557996 - Make HTMLEditor::GetSelectedElement() not treat an element as selected when it's followed by a <br> element r=m_kato
Currently, `HTMLEditor::GetSelectedElement()` is not used in mozilla-central
and mainly used for handling double clicks in the editor with its complicated
path.  In most cases, users don't want double clicks to cause showing
property dialog in mail composer.  Therefore, we must be able to stricter in
the complicated path.

This patch adds new check whether the selected range ends immediately before
a `<br>` element.  If it's end at a `<br>` element, we shouldn't treat found
element as selected.

Note that when `<a href="...">` element is double-clicked, the element itself
is selected like `<img>` element.  So, we don't need to worry about the case
which is that users probably want to update a link with double-clicking since
such case is handled by the first optimized path in the method.
