This ensures that on iOS builds that can paint a switch, the following
tests pass as expected:

- fast/forms/switch/zoom-approximates-transform-rtl.html
- fast/forms/switch/zoom-approximates-transform-vertical-lr.html
- fast/forms/switch/zoom-approximates-transform-vertical-rl.html
- fast/forms/switch/zoom-approximates-transform.html

Without this fix there would be some amount of zooming on iOS due to it
currently aligning with the font-size, but only for very large zoom
values.

Also add a new test that demonstrates this does not impact
getComputedStyle() across platforms.
