Alert dmx-show query parameter not working

I’m not sure if there is a bug but I have a simple BS4 alert and I want to show it when the page query parameter is: logout=true.

I’ve tried with Dynamic attributes dmx-show but it’s simply not working. dmxBootstrap4Alert.js is loaded correctly as the alerts are showing when set to AutoShow.

<div class="alert" id="alert1" is="dmx-bs4-alert" role="alert" dmx-show="(query.logout == &quot;true&quot;)">
				<p>This is a nice alert!</p>
			</div>

logout is also set as a variable under page query parameters.
