Creator - Question Title Charactor Limit

We are currently trying to accomplish the following when adding a new Question - we want to limit the character count.

In the Creator,
prevent the question title being more than 50 chars long in the Designer ( When adding a question ).
prevent the question title being more than 50 chars long in the General tab ( Right of screen ).

Note: we are not showing the validation expressions as we have hidden them from view.

General tab,
Wont allow more than 50 chars in the title field ( Correct )
Copy and paste more than 50 chars into the field, it will cut off anything after 50 chars ( Correct )

Designer,
Wont allow more than 50 chars in the title field ( Correct )
Copy and paste more than 50 chars into the field, it will NOT cut off anything after 50 chars ( Wrong )

"survey-core": "^1.9.52",
"survey-creator-react": "^1.9.52",
"survey-react": "^1.9.52",

This is what we are using to limit the charactors

TypeScript
 var maxTitleLength = 50; 

SurveyCreator.
   onPropertyValueChanging
   .add((_sender, options) => {

       if(options.propertyName=="title"){
           if(options.newValue.length >= maxTitleLength){
               options.newValue = options.newValue.slice(0,maxTitleLength-1);
               options.value = options.newValue.slice(0,maxTitleLength-1);
           }
           // if null, or whitespace, then reset to name
           if(options.newValue.length == 0 || options.newValue.match(/^ *$/) !== null){
               options.newValue = options.obj.name;
               options.value = options.obj.name;
           }      
       }
   });
