Thank you for contacting Telerik support.
Examining the provided custom tags, I see that they are used with a contenteditable
attribute set to false
. By that the browser is instructed that these tags are not editable and it is expected to not be able to delete any text inside.
I can only assume how these tags should be used, although, if you need content to be editable inside, I suggest removing the mentioned attribute configuration.
Let me know if I can help further on the matter.
