No word-break in url´s

[Doctor Asp]

I believe I´ve found a bug.
Default theme, english, no mods.

When I reply to a post, I get a page with the editor and a "Topic summary". In this summary url´s or other very long words don´t break but continues off the screen.
Tested in iPhone, Android, Chrome, Edge and Firefox.

Chrome:
You cannot view this attachment.

Edge:
You cannot view this attachment.

In standard topic view the url breaks as expected:
You cannot view this attachment.

Lol. Another CSS oversight. Add it to the list.
