Original Bootstrap issue: <a href="https://github.com/twbs/bootstrap/issues/16809">https://github.com/twbs/bootstrap/issues/16809</a>

Setting `display: block; width: 100%` on an &lt;input type=&quot;range&quot;&gt; causes the left or right part of the &quot;thumb&quot; of the input to get clipped when the user moves the &quot;thumb&quot;.

Test case: <a href="http://jsfiddle.net/cvrebert/0uzk6f4c/">http://jsfiddle.net/cvrebert/0uzk6f4c/</a>

Steps to reproduce:
1. Open <a href="http://jsfiddle.net/cvrebert/0uzk6f4c/">http://jsfiddle.net/cvrebert/0uzk6f4c/</a> in OS X Safari
2. Click on the range input's &quot;thumb&quot; and keep the mouse button depressed
3. Move the mouse to the left or right sufficiently so that the &quot;thumb&quot; changes its position along the range input's &quot;track&quot;
4. With the mouse button still depressed, move the pointer downward so that you can see the entire &quot;thumb&quot; unobscured

Expected behavior:
The range input's &quot;thumb&quot; should be drawn normally.
(In Safari's current UI, it should be a white/gray circle.)

Actual behavior:
The range input's &quot;thumb&quot; has its left or right edge clipped off.
See attached screenshot.
