onContentSizeChange on TextInput does not trigger in some cases #1339

The problem

When <TextInput /> has an explicitly set height (for example because we're implementing an auto-growing textarea) then onContentSizeChange is not being triggered if the content height is smaller than that container height.

How to reproduce

Expected behavior
onContentSizeChange is called again with the correct values

Environment (include versions). Did this work in previous versions?

  • React Native for Web (version): 0.11.2
  • React (version): 16.8.6
  • Browser: tested on Chrome

Additional context
The workaround I've used in my particular implementation:

  if (Platform.OS === 'web') {
    const node = this.input._node = 'inherit'
    const height = node.scrollHeight = `${height}px`
    this.setState({ height })
