Set text-rendering to 'auto' when font shorthand is used in html.css.

Set text-rendering to 'auto' when font shorthand is used in html.css.

There is currently a bug causing invisible tabs whenever text-rendering:
optimizeLegibility is used. Until recently, we (accidentally) over-wrote
the text-rendering property when font shorthands were used, effectively
masking the problem for the matching elements.

This patch adds text-rendering:auto to html.css, for compatibility.

Should we do this?

I can see how for example code-editor apps might be affected by the bug/change,
where tabs plausibly could be present.

Of course it's better to fix the tab+optimizeLegibility bug itself, but I
currently have no idea how difficult that is, and automated
releaseblocker-nag-emails have successfully instilled a sense of urgency.

I think this is fine, lgtm.
