Text entry in the image settings bottom sheet is difficult. It's a small space and confined to a single line. To proofread or change the text, you have to scroll horizontally.

It would be good to improve this text entry for long text, e.g. have the text field expand vertically as you type.

As tested on iPhone XS, iOS 12.2, WP 12.2.0.20190412.

h/t @ryanboren for raising this issue.
