Styles breaking ‘background-attachment: fixed’

I have confirmed there are styles set by this plugin which can break the background-attachment: fixed CSS property. This means if you want to assign a parallax background on blocks, it will not work on the front end if you have this plugin activated.

File:
/off-canvas-sidebars/slidebars/slidebars.css

Lines 120-123:

[data-canvas], [data-off-canvas] {
	-webkit-transform: translate( 0px, 0px );
	    -ms-transform: translate( 0px, 0px );
	        transform: translate( 0px, 0px );

These lines cause the CSS property background-attachment: fixed to stop working.

When the lines are removed or overridden, everything works as expected:

[data-canvas], [data-off-canvas] {
	-webkit-transform: none !important;
	-ms-transform: none !important;
	transform: none !important;
}

I am not sure if these are actually required to have the Slidebars menu working — when I apply the overrides, the side menu and everything else still works fine for me.

I hope this is helpful for other users who have run into this problem.

Hopefully a fix for this can be released soon.

Thanks!
