Summernote Lite Textarea Validation Not Working

Wappler Version : 5.1.0
Operating System : Windows 10

Expected behavior

1. Add Validation rules in the properties of a Summernote Lite Textarea

2. In the Actions Editor (f.e. in Dynamic Events), the “Validate” Action for the Summernote Lite Textarea shows up for selection

Actual behavior

1. Add Validation rules in the properties of a Summernote Lite Textarea

2. In the Actions Editor (f.e. in Dynamic Events), there is no “Validate” Action for the Summernote Lite Textarea
   

Alternatively, I have attempted to insert the validation manually in the code (with dmx-on:click="input_description.validate()") but that doesn’t appear to work either.
