at getOrCreateInjectable (D:\dev\proj\demo-angular-project\dist\demo-angular-web\server\main.js:129551:10)I think when prerendering a page on server side, it's initializing _hmt. which is meaningful. should we skip that if we can detect it's in prerendering process to make the libarary more robust.
