inserting Emoji to my subject and push message both are rte in one component, emoji displays at both places subject and push message while inserting at second column(vice versa)

Hello Everyone,

The below screen AEM componet has two columns one for headline/subject and other for push message. When author tries to add emoji at first column(healdine) emoji renders as expected place but when he goes at second column(push message) and tries to add emoji then it renders at starting position with irrespective location and it happens for both columns as highlighted. This can happen when you tired to edit the second rte. does anyone came across of this issue? AEM 6.5.8.0 version

This is how message center component is configured in crxde lite.

Any help is much appreciated..thanks in advance
