Drag & Drop designer control visibility by expression with field IS NOT NULL doesn't work if the field is configured with html #47363

What is the bug or the crash?

Using Drag & Drop Designer Control visibility by expression Doesn't work when is based on a html_field IS NOT NULL expression and the html_field widget is configured with the HTML checked like in the image. I've attached a test project. If I untick the HTML option then the rule works as it should and the Bug Group is hidden.

Steps to reproduce the issue

  1. Download the attached project visibility_by_expression_bug.zip

  2. Open the form of the point and you shouldn't see the Bug group as the expression should have hidden it.

  3. If you untick the HTML box in the textedit widget it works.

Tried also with master build from source just now.

@tudorbarascu just to point out that if you uncheck HTML it does not completely work because there is no way to go back to NULL once you have typed something in the text edit.
