Current behavior

When I paste a long base64 string into a request body or query parameter of a specific content type, the program interface freezes and does not respond to any of my operation.

Steps to reproduce

1. Create an arbitrary request
2. Paste the base64 string at the end of the text in the Query Parameters, or in the Request Body of ContentType = application/x-www-urlencoded
3. The interface freezes and does not respond to any operation

The base64 string for the test is in the following text file:
base64.txt
