Steps to reproduce the problem:
1. Write something in a field

What is the expected behavior? (add screenshot)
The 3 fields must have the same value

What went wrong? (add screenshot)
The 2 other fields are empty

The three fields share the same name `Text3`.
It works as expected in Adobe and Chrome.

      container.style.borderWidth = `${data.borderStyle.width}px`;
      if (data.borderStyle.style !== AnnotationBorderStyleType.UNDERLINE) {
        
        
        
        width = width - 2 * data.borderStyle.width;
        height = height - 2 * data.borderStyle.width;
      }
      const horizontalRadius = data.borderStyle.horizontalCornerRadius;
      const verticalRadius = data.borderStyle.verticalCornerRadius;
      if (horizontalRadius > 0 || verticalRadius > 0) {
        const radius = `${horizontalRadius}px / ${verticalRadius}px`;
        container.style.borderRadius = radius;
