TW core typo

[RA]

#backstageCloak {background:[[ColorPalette::Foreground]]; opacity:0.6;
filter:'alpha(opacity:60)';}

The end should be {...;filter:alpha(opacity=60);}

[RA]

And another, extra space in "! important"

@media print {
#mainMenu, #sidebar, #messageArea, .toolbar, #backstageButton,
#backstageArea {display: none ! important;}
#displayArea {margin: 1em 1em 0em 1em;}

> And another, extra space in "! important"
