3210715 - Spell Check is not working on Edge/Chrome for some of the webdynpro field, e.g., TextEdit control

Spell Check is not working on Edge/Chrome, e.g., TextEdit control on Webdynpro.

On IE, when the function is enabled, can see the red line under the word, and if right click on it, can do the spell check.

On Edge or Chrome, can only see the red line after enabling the function from browser or OS, but it doesn't have the context menu for spell check once right click on it.
