Before this commit when computing the deepest position for a non-visible
node, if that node had no next visible sibling it used the previous
siblings, but it still marked the offset within that sibling as 0.
Because of this, the selection sometimes got lost.
E.g. in Firefox, drop an "Image - Text" block and triple click on the
header text: upon changing its color the range got set to the text node
but ending at offset 0.
After this commit if the used node in the "previous sibling" from the
evaluated element, the offset is set to the length of that node.
