BUG: Cant use Browser back function

[breadlesscode]

Behaviour

If you press the browsers back button on the import or export page you got the unrendered markup.

Expected

See the backend module.

Reproduce

1. Visit redirect handler backend module
2. Click on export redirects
3. Press the back button in your browser

Can't reproduce with Brave or Safari and also I'm not sure why this should happen.
The export and import pages are normal controller actions and nothing JSy.

Any other hints you can give me?

Safari: 13.0.3 - ✅ Works

Sorry I also have no good Idea why this happens. If you are open DevTools and have Disable Cache on, you cant reproduce this error! Its the internal Browser cache that produces this error. It thinks the last response was a application/json-Response, but its a small HTML-Partial.

Ok thx! I'll test again.

I was once able to reproduce and now I can't again with any browser...

Fix in neos/neos-development-collection#2841

[Sebobo]

Fix was just merged into Neos and will be in the next patch release. Therefore I'll close this.

Thank you for taking care of it :)
