Vendor prefix getting removed when getting css from getCss()

I am using the version: 0.14.57 with React 16.8.6.

When I use the function editor.getCss() it returns me the css but without the vendor prefix. For example, I add the following css .product-card { -webkit-transition: all 0.2s ease; transition: all 0.2s ease; } it returns me .product-card{ transition-duration:0.2s; transition-timing-function:ease; transition-delay:0s; transition-property:all; }. How can I avoid this behaviour and get what I am saving (with the prefix)? I checked this in the demo, it works fine there but with my local I am having an issue. Unfortunately I can't publish it else where and don't have it live atm. It's just this one, getCss() function that's causing the issue. Following is my initialization:

let editor = GrapesJs.init({
	container: "#gjs",
	fromElement: true,
	plugins: [
	'gjs-blocks-basic',
	tUIImageEditor,
	GrapeJSFormPlugin,
	editor => FontAwesomePlugin(editor, {}),
	editor => SocialMediaPlugin(editor, {}),
	editor => VideoPlugin(editor, {})
	],
	canvas: {
		styles: [
		"https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css",
		"https://fonts.googleapis.com/css?family=" + fontFamilies,
		"https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.11.2/css/all.min.css"
		],
		scripts: [
		"https://code.jquery.com/jquery-3.3.1.slim.min.js",
		"https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js",
		"https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js",
		'https://use.fontawesome.com/145d2bb38b.js'
		]
	}
});

I'm applying the styles with editor.setStyles(css). It sets fine but when I retrieve it, it removes the prefix. Any help would be appreciated.
