Cannot set initial height of textarea
it's unintuitive that you can set the initial width of the textarea but not the height. This is useful for cases where you might want to have a reserved spot for the text but no initial text.
I fully agree. Right now the textarea grows with the text... a useful feature in some circumstances, but a preferred default behavior should probably be a fixed height and width and scrolling of overflow content.
I hadn't thought about that, but you're right that the html default for textarea is just as you said: fixed height with overflow scrolling.
I actually like that the textarea grows with the text. I would just like an empty textarea to initially appear multiline despite having 0 lines of text.
Yes, we liked it as well, that's why a height property was never implemented :) One option would be a min-height property and a height property that can be set to auto. If you choose to implement something, please feel free.
