If this issue only occurs in one browser, which browser is a problem?

Tested in Firefox, Safari, and Edge. Seems to be a cross-browser issue.

Describe the Bug

When navigating using the <ClientRouter>, elements using Declarative Shadow DOM via the shadowrootmode attribute on <template> elements, are not rendered.

What's the expected result?

These elements should render the same as they do on an initial page load.
