Inserting a new line after a link typically adds a new line and removes the copied link.
However, this does not work when paragraph is about to be split.
For the time being you can override the _nodeInsertedHandler method to resolve the bug as in this example:
<telerik:RadEditor runat="server" ID="RadEditor1">
<Content>
<p><a href="http://www.telerik.com" >link</a>text</p>
</Content>
</telerik:RadEditor>
<script>
Telerik.Web.UI.Editor.InsertParagraphCommand.prototype._nodeInsertedHandler = function (args) {
var command = this,
cursor = args.get_cursor(),
container = args.get_container(),
isEmptyContainer = command._isEmptyContainer(container, cursor),
$E = Telerik.Web.UI.Editor,
utils = $E.Utils;
var parentAnchor = utils.getElementParentByTag(cursor, "A");
if (command._isEmptyContainer(parentAnchor, cursor))
command._removeNode(parentAnchor);
if (isEmptyContainer) {
if (command.get_editor().get_enableTrackChanges()) {
var tcUtils = $E.TrackChangesUtils,
parentTrackedInsert = tcUtils.getParentTrackChangesInsertNode(cursor, container),
parentTrackedDelete = tcUtils.getParentTrackChangesDeleteNode(cursor, container);
command._removeNode(parentTrackedInsert);
command._removeNode(parentTrackedDelete);
}
}
};
</script>
