Describe the bug
Direct-link popup doesn't work when Debug is enabled in .env file.

Steps To Reproduce
Steps to reproduce the behavior:

Edit .env
Set APP_DEBUG=true
Re-load a page
Select text

Expected behavior
A popup with the URL to the page or selection should appear.

Actual behaviour
No popup

Your Configuration (please complete the following information):

0.23:
PHP Version: 7.0.27.9+deb9u1
Using Docker or reverse proxy (Yes/No): Yes (Nginx rev proxy)

Additional context
More of a documentation bug maybe? A comment added before the APP_DEBUG line in the .env file to the effect that it breaks the popup might suffice? I was scratching my head for a while, before I remembered I'd set the debug option to help get wkhtmltopdf working.

@gareththered Thanks for reporting this issue but I am not able to re-produce this bug.

When setting APP_DEBUG=true the popup still shows as expected. Tested on Ubuntu 18.04, chrome & firefox.

Can you confirm your browser and OS?

I'm running Windows 10. After a little digging around, it seems this only happens on the Chrome browser. Edge/IE and Firefox work fine.

@gareththered Thanks for confirming. I'm wondering if this could possibly be due to a conflict with a browser extension you have?

Could you try in an incognito window (If you have extensions disabled when incognito)?

It seems that Incognito mode does work. So does normal mode with all extensions disabled. However, trying to narrow down which extension using split-half brings inconsistent results. At least we know its a browser extension issue.
