[PATCH] css: make highlight div absolute and top left

[Andy Green]

Normal operation of blame view requires div.highlight to
have absolute position and set to its parent's top left
for me.

Otherwise the grey background boxes indicating the extent of
the patch in the lines td displace the highlit sources, they
start at the bottom of the td.

This patch makes the highlight div start back up the top of
its parent area and render on top of the grey boxes.

Checked on Linux Firefox 60 and Linux Chrome 69.
