Safari white screen affected from regular expressions of dist/static bundles when npx@backstage/create-app locally

[arlindhoxhaa]

Expected Behavior

Would like to see all the content of Backstage when opening it locally on Safari.

Current Behavior

I see the white screen in Safari, but when actually trying to open the Backstage with another browser for example Google Chrome, then it's running perfectly.

Possible Solution

Check used regular expressions which are causing this..

• Operating System and Version (e.g. macOS Big Sur):
• Browser Information: Safari

Thank you for reporting; this is indeed related to the other issue and I'll close in favor of that one to keep the discussion in one place.
