Use a div with attribute:
 - contenteditable="true"

It fixes a lot of issues:
 - height of #input needs no javascript to adapt to content
 - therefor no complex styles are needed
 - width will no longer exceed the given width by grid-template-column
 - styling etc. can be handled like the #output div next to it

You have to set two attributes for a11y:
 - role="textbox"
 - aria-multiline="true"

to look like the rest it must be set thicker back to default focus
outline.

As the busy dialog most of the time is very short a backdrop tends the
whole page to flicker. To avoid that let it original w/o backdrop.

Otherwise there would be a much greater gap between header and main.
Header normally is styled by icluded style via head.php. This has the
correct margin. The padding-top from this local style.css did two gaps
together.
