Nice cleanup 🙌🏻
A few points from my side:

• Can we make this a design-system component? Current implementation includes a few specific things, like releaseChannel and location that we can abstract away and pass color, showLogoText and showReleaseChannelTag as props
• Maybe also moving logo creation logic from onMounted into a composable would make it easier to mock in the test if there is no other workaround for jsdom issue
