link is duplicated on table row insertion

Adding rows to a table, while focusing a cell with a link, duplicates the link into the inserted row.

steps to reproduce:

• on a xmlblock field, insert a table, with 3 rows x 3 columns
• on the first cell, type some text, convert it to link, select a node for it to link to
• without moving the focus, click on the insert row after button
• select the first cell from the new row (directly below) and start typing
• you'll verify that the text being entered in underline as if it were a link.
• disabling the editor, you'll verify that the link as been duplicated

workaround

empty the new row's cell (backspace) will erase the undesired link
