Original Bootstrap issue: <a href="https://github.com/twbs/bootstrap/issues/16814">https://github.com/twbs/bootstrap/issues/16814</a>
It seems that WebKit/Safari places position:fixed elements incorrectly when they do not have a left/right/top/bottom property set on them and are a child of an element that is position:relative;left:X%;
See the attached screenshots. Safari renders the example differently from Chrome. IE11 and Firefox give the same result as Chrome.
To reproduce:
1. Open <a href="http://jsbin.com/rohemer">http://jsbin.com/rohemer</a> in OS X Safari or iOS Safari.
2. Look at the red paragraph's text.
Actual result:
The red paragraph's text doesn't quite make sense, because part of it isn't visible.
Expected result:
The red paragraph's text makes sense because all of its text is visible.</pre>
