On first load the toolbar gets hidden underneath the navigation side (nav.mp4). Resizing the browser window the value for the left attribute of the canvas gets correctly updated from:
<div class="canvas" role="application" aria-label="BPMN Canvas" style="top: 142.156px; left: 48px; width: 1880px;"><div class="bjs-container" style="width: 100%; height: 100%; position: relative;">

<div class="canvas" role="application" aria-label="BPMN Canvas" style="top: 142.156px; left: 48px; width: 1880px;"><div class="bjs-container" style="width: 100%; height: 100%; position: relative;">
If you reload the page the toolbar gets hidden again. Problem applies to latest Safari, Firefox and Edge on macOS Sequoia.
It looks like the initial values set in the event listener in bpmn_io.js are not acknowledging the navigation sidebar.

Yeah, I've noticed that as well. Looks like the new toolbar from Drupal core brings a few new paradigms that we need to get acquainted to. We'll address this when all of that is more mature, and then we also need to see that Gin is ready to support the new navigation framework as well, so that we can catch both flies with one stroke.
