Selection is being displayed incorrectly around the linkHref nodes

[pomek]

Something wrong happens around links. Check out screenshots attached in the issues listed below:

• 2SCM fails when moving the selection inside the text ckeditor5#7568 ("amet" is highlighted, inspector renders selection after the node)
• Autolink behaves incorrectly when modifying a link at the end of the element ckeditor5#7588 ("CKSource." is highlighted, inspector renders selection after the node)

Can you write this as expected vs actual? I'm having a hard time figuring out what the problem is.

In both cases, editor's selection is at the end of a link. The inspector shows it outside, in the next node.

There's no such thing as a selection in the textnode in the model. <$text linkHref>foo[]</$text> and <$text linkHref>foo</$text>[] are one and the same position. So from this perspective, the inspector does not lie.

What could be improved, though, is the normalization of the caret rendering because I admit this could be annoying in certain situations.
