Addons-frontend: The add-on and author's name are too close

[ioanarusiczki]

STR:

1. Submit an add-on that contains "y" "q" "p" "g" in it's name
2. Go to the add-ons detail page
3. Observe the Add-on details section

Expected result:
It's a reasonable space between the Add-on's Name and Author.

Actual result:
The two names are too close, they look jammed in.

Notes:
This issue is reproducible on AMO dev and AMO stage with FF59 (Win10).

I'll give below two examples to make it more clear

and another one
