SVG will break (using YUI)

Problem/Motivation

Activating aggregation will break the svg icon of the menu "toggler" of a bootstrap theme

Before, works
url("data:image/svg+xml,%3csvg viewBox='0 0 30 30' xmlns='http://www.w3.org/2000/svg'%3e%3cpath stroke='rgba(255, 255, 255, 0.5)' stroke-width='2' stroke-linecap='round' stroke-miterlimit='10' d='M4 7h22M4 15h22M4 23h22'/%3e%3c/svg%3e")' stroke-width='2' stroke-linecap='round' stroke-miterlimit='10' d='M4 7h22M4 15h22M4 23h22'/%3e%3c/svg%3e)

After, does not work
url("data:image/svg+xml,%3csvgviewBox='003030'xmlns='http://www.w3.org/2000/svg'%3e%3cpathstroke='rgba(255,255,255,0.5)'stroke-width='2'stroke-linecap='round'stroke-miterlimit='10'd='M47h22M415h22M423h22'/%3e%3c/svg%3e")'stroke-width='2'stroke-linecap='round'stroke-miterlimit='10'd='M47h22M415h22M423h22'/%3e%3c/svg%3e)

Only if you use YUI Compressor.
