<agent_instructions>Multiline TextInput is creating more space than needed and wrapping in weird ways while typing

Issue Details:

• Multiline TextInput shows excessive empty vertical space below the text content
• Text wraps earlier than expected, not using the full available width
• The problem occurs even without padding/contentInsets defined
• When typing, the TextInput grows larger than necessary to accommodate the text
• The wrapping behavior is inconsistent - text breaks to new lines before reaching the edge

Visual Symptoms:

• Large blank area below the last line of text
• Text wrapping prematurely (not reaching the right edge before wrapping)
• TextInput height is larger than the actual text content requires

Expected Behavior:

• TextInput should only be as tall as the text content needs
• Text should wrap at the full available width (minus any padding)
• No extra whitespace below the text</agent_instructions>
