Edit Link button not working in Firefox

[Brylie Christopher Oxley]

Current behavior?

When clicking the anchor next to an existing link and then clicking the 'Edit' button, nothing happens. There are some errors in the console, but the code has been minified.

Steps to reproduce

1. Create or edit a Wagtail page using Firefox
2. Insert a link
3. Click the anchor icon next to the link
4. Click the 'Edit' button in the popup

Expected behavior

The edit modal should appear, but doesn't

Environment

Wagtail 2.2
Firefox 61.0.1 (64-bit)
Kubuntu 18.04

Hey @brylie, thanks for reporting this.

I can't reproduce what you are describing in my local environment (Firefox 61.0.2 (64-bit), Wagtail 2.2.2, macOS 10.13).

Could you:

1. Re-open this on the Wagtail issue tracker. Any issue with Wagtail should be reported there first (that's where others will look for it, and the link feature you're using is Wagtail's).
2. Provide the errors you see in the console.
3. If you think that can help – provide more extensive repro steps, or perhaps a recording of your interaction with the page. Your report specifically says "clicking the anchor" so perhaps there is something about clicking on specific pixels that I didn't manage to trigger when testing it myself.

Additionally, Wagtail comes with source maps since a recent release (either 2.1 or 2.2, I'm not sure) so if you have the browser developer tools open you should be able to see the error with the un-minified source.
