After _syncHeightWithShadow is called on componentDidMount in the enhanced-textarea.jsx component, it will revert from initial 24 value to 0. As a result, the user is completely blocked from editing the textarea.

I managed to temporarily fix it by changing this line:
https://github.com/callemall/material-ui/blob/master/src/enhanced-textarea.jsx#L123

To:

if (this.state.height !== newHeight && newHeight !== 0) {
