I'm using the standard EE 'Textarea (Rich Text)' field (on EE 2.10.1), but no matter what I put in the 'Textarea Rows' field, when viewing the field in the control panel it's only around 150 pixels tall.
I can of course drag the bottom right hand corner of the field to make it display more of its contents but it's a pain to have to do this each time.
Is this a known bug or is there a way to get this field to display deeper?
