Text in "Share your profile" image is missing spaces when copied from Firefox

[stromfeldt]

Issue Summary

Although the "Share your profile" image looks fine when copied from Safari and Chrome, the text of both the user name as well as the body are missing spaces when copied from Firefox. (To be clear, the preview looks fine, but the copied and pasted image does not.)

Steps to Reproduce

1. Click the "copy image" button on the "Share your profile" page while using Firefox.
2. Paste the image into another program, and see that spaces are missing within the text of the user name as well as within the text of the body

I've transferred this issue because it's activitypub specific, although it's related to the Ghost portion of code. Not sure if that's right, just trying to get the correct eyes on it!
