RTE Max no of Chars.

Hi All,

I have a dialog where it has multiple tabs which contain CTA links and RTE fields.
My question is I have a description where it is a RTE and List items tabs where author can add any number of list items. And these list items are RTE multi field. max length required for both is different (lets suppose description - 30 and list items- 40 max chars) . 

I have multiple scenarios 

1.So when I set those limits by writing custom validation  , for description it is working fine where as for list items it is showing the limit alert but not displaying the content. 

2. if i check max char for description  and list items it gives an alert when exceeded and when go back to description to check again, list items max char length alert is showing up and vice versa.

please help.
