[6.2.7] Stoorybook does not refresh after save

[softshipper]

Hi all

I have created a Storybook and after when I change something and save it, the browser does not refresh automatically. So every time I have to press the F5 button.
Unfortunately, I could not figure the problem.
Here are the files:
components.zip

Thank

I have figured out that on Firefox hot reload works like a charm. However, on Chromium hot reload does not work at all. I am using https://pop.system76.com/ as OS and Chromium is installed with flatpak.

When I start the storybook, in the terminal it shows me:

Nothing looks odd about those warnings FWIW

I have installed Chromium via https://flatpak.org/. May that is the reason, why it does work.
