JQuery Mobile textarea: how does it use 'rows' attribute?

Question

I would like to dynamically generate textareas, with JQuery Mobile, with varying numbers of rows. I was intending on using knockout for this, data-bind to the rows attribute.

E.g. here: http://jsfiddle.net/j7b9A/2/

<label for="textarea-1">5 rows:</label>
<textarea rows="5" name="textarea-1" id="textarea-1"></textarea>

<label for="textarea-2">10 rows:</label>
<textarea rows="10" name="textarea-2" id="textarea-2"></textarea>

However, JQuery Mobile seems to ignore the rows attribute, which is well-documented: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/textarea, and is even included in JQuery Mobile's own documentation: http://view.jquerymobile.com/1.3.1/dist/demos/widgets/textinputs/index.html#Textarea.

A comment here states that setting the height and width overrides the rows attribute: https://stackoverflow.com/a/7194692/1061602. It seems that it is because JQuery Mobile is doing a transition when the textarea expands. So is rows attribute always being completely overridden?

Another similar question is here: How to make text area to be height of 10 rows fixed?, but this doesn't help me as I don't want to fix the height of all textareas, I would like them to vary, as they can normally using the rows attribute.

Also what I have noticed, which I can't explain, is that in my own code, a rogue style="height: 184px;" is added to one of my textareas, but not another. The other just uses the standard style of 50px, as highlighted in this answer: jQuery Mobile and textarea rows - this would seem to indicate there is something else going on, but I can't reproduce this yet in a simple fiddle.

I've had a quick look at the JQuery Mobile source but I can't see the rows attribute being used at all?

What would be the best way of specifying a range of row heights for a range of bound JQuery Mobile textareas?

all you need is... add this

textarea.ui-input-text { height: inherit !important}
