//webkit & Chrome22+ special case
//webkit is not following the standard specs as of Chrome22+
@media screen and (-webkit-min-device-pixel-ratio:0) {
	//like it happens in Firefox&IE, we expect when we set "z-index:auto" for fixed position .sidebar,
	//the child .submenu elements "z-index" is independent
	//and for example a "z-index:1031" .submenu appears on top of a fixed .navbar with "z-index:1030"
	//and a "z-index:1010" .popover appears on top of ".sidebar" but below ".submenu"
	//but webkit defines a new stacking context on "fixed" position elements(.sidebar here)
	//and the above doesn't happen, in fact .submenu inside fixed .sidebar with "z-index:auto" will appear below everything
	//so we set a good(?) "z-index" for .sidebar, but still it's not as good as standard specs (such as in Firefox)
	//and we may need other workarounds!
	//and you may change it based on your needs

	//it's possible have standard functionality in Chrome by going to:
	//chrome://flags/#fixed-position-creates-stacking-context
	//changing "Fixed position elements create stacking contexts" to "Disabled"
	//and removing the following rules
	//and assignning a higher "@submenu-zindex"

	.sidebar.sidebar-fixed {
		z-index: @zindex-sidebar-fixed;//???!
		
		&::before {
			height: 5000px;
			top: auto;
			bottom: auto;
