Help settings / HTML editor

When choosing data type -> HTML editor in a form app, the help settings does not seem to be active.
When I fill out the help settings there will not be added any help.
It does not matter which help type I choose.

Any comments ??

The “watermark” function is missing (It might never has been there but … ) … It would be great if the “watermark” function could be enabled for this data type as well !!
