Base64 function(s) get lost in subsequent edits of a Logic App

Describe the Bug with repro steps

This bug has been around for a while;

https://feedback.azure.com/d365community/idea/e9976e92-7b26-ec11-b6e6-000d3a4f032c

It's also affecting the new designer, not just legacy.

The steps to reproduce are;

• Enter a base64() function (or base64ToBinary, etc) in the Logic Apps designer, save and close
• Open the Logic Apps in the designer again and see the base64() is gone.
• Open the Logic Apps in code editor and see the base64() is actually still there

This is problematic since the base64() function gets lost if I edit something else on UI editor & save the changes.

Once you use the base64() function, you have to keep re-adding it via the code editor or enter the base64() again through the designer before saving.

If you copy/paste the expression in the designer, it won't include the base64 function, leading to issues if you copy/paste into other fields or another Logic App.
