Refreshing twice quickly causes browser tab to freeze

[ohenrik]

Refreshing twice in rapid succession causes the browser tab to be unresponsive. It is also impossible to force close this tab or killing it when Chrome asks about unresponsive tabs.
Shutting down npm run start -s does not help either. Opening the project (localhost:3000) in another tab results in two frozen tabs.... (cursing at my screen also does not help...).

After about 5 minutes (!) the tab finally responds and is closed.

To Reproduce
Unsure if this is spesific to my project, but try to refresh the page multiple times in rapid succession.

Expected behavior
Browser tab should not freeze for 5 minutes... Coffee breaks are fine, but I'm already shaking from all the caffeine.
