Attribute names are lowercase

Hi,

I used a preact component in amp-script tag and I noticed that my inline SVG has viewBox attribute all lowercase after hydrating. It is allright in non-AMP page with the same component and preact.

<svg version="1.1" viewBox="0 0 22 22" xmlns="http://www.w3.org/2000/svg">

<svg version="1.1" viewbox="0 0 22 22" xmlns="http://www.w3.org/2000/svg">

There are probably more case sensitive attributes (preserveAspectRatio).
