App does not show up before switching to other tab and back

[pony1k]

When I open the app in a fresh browser tab, the page shows "Loading..." and does nothing, until I hit refresh, switch to another tab and back, minimize the browser window or something similiar. Here is a screenshot of the app with firefoxes network monitor, if that helps. The last 4 requests appeared just after switching back to the tab.

I'm using the current develop branch (5113561). This happens with firefox 121.0.1 as well as chromium 120.0.6099.224 (Official Build, ungoogled-chromium).
