Steps To Reproduce

1. Create a TextInput, then set the multiline props to true and leave the placeholder value empty.
2. Set a timeout to run a function that will set the placeholder value to a certain text.
3. On time out, the placeholder will remain empty.

Expected Results

On time out, the placeholder should show up with the value similar to the text set.

Interesting, thank you for the repro!

I was able to reproduce it, the placeholder prop is not handling updates correctly.

Dynamic placeholders can be fixed by using ' ' (space character) as the empty value instead of an empty string ('') or undefined.
