Before you start - checklist

• I followed instructions in documentation written for my React-PDF version
• I have checked if this bug is not already reported
• I have checked if an issue is not listed in Known issues
• If I have a problem with PDF rendering, I checked if my PDF renders properly in PDF.js demo

Description

There is a functionality available in pdf.js that allows for automatic calculations within PDF form fields if formulas are set. When a PDF form field changes value, the calculations are triggered, and the results are automatically updated in the respective form fields. However, this feature is not currently available in react-pdf.
