With “Enable the latest RichTextEditor control experience in the default controls” turned on from the Model Driven App settings, the editor height does not automatically scale with input values in the new design.
We have confirmed that the workaround is to change to the old design or turn off the relevant feature.
However, if this feature is turned off, when attaching a file to a RichTextEditor control, the word “undefined” will be inserted before the file in the field when attached to the classic editor.
Also, when attaching a file to a RichTextEditor control, an error occurs in the Classic Editor if the file size exceeds 5 MB.
Therefore, we would like to have the RichText field automatically expanded in the future when the relevant function is turned on.
