* Fix \sqrt zoom in Safari

This PR evades a Safari bug which causes nested SVGs to zoom improperly. `\sqrt` and single-ended arrow SVGs have been modified.

These have been converted from nested SVGs to single level. Their long tails are now sliced off using CSS `overflow: hidden`.

Safari will still improperly zoom any double-ended stretchy arrows and horizontal braces.

* Fix \sqrt{}

Even if the function argument is empty, still render an SVG whose width equals the surd glyph.

* Fix tall \sqrt when scaled

* update screenshots affected by sqrt fixes

* more screenshots after changes to fix sqrt

* Pick up review comments
