Remove newline in textarea generated by HAML / Form Builder

I have a very simple Rails form.:

= form_for @object :remote => true do |form|
   = form.text_area :text, :class => 'form-control'

For a new object, with a nil text attribute, this generates:

<textarea class="form-control" name="object[text]" id="object_text"> </textarea>

The blank space in that is a newline:

(byebug) form.text_area :text, :class => 'form-control'
"<textarea class=\"form-control\" name=\"user_deactivation[reason_text]\" id=\"user_deactivation_reason_text\">\n</textarea>"

I strip out the leading and trailing spaces on save, so data wise, its not a big deal, but when the user clicks on this field, it appears indented.

enter image description here

Relevant software versions:

Why is this newline being generated and how can I stop it?

You can use the '~' operator, which is like the '=' operator, but automatically runs find_and_preserve on the output.

Like this: = form_for @object :remote => true do |form| ~ form.text_area :text, :class => 'form-control'

This is not an ideal answer, but it does work. I would like something better:

 = find_and_preserve(form.text_area :text, :class => 'form-control')

Can that be automatic? Is there a way to have the text_area helper not insert a newline?
