Problem has been reported by a user on dewiki, I can replicate it. Seems like a recent change.
**Steps to replicate the issue** (include links if applicable):
* Open a WP page in Minerva skin, e.g. [[https://de.wikipedia.org/wiki/Paul_Gleeson?useskin=minerva]] in an incognito window.
* Scroll to the page footer and identify the last-modified bar ("Zuletzt bearbeitet vor …").
* Reduce the screen width to below 1000px.
**What happens?**:
The last-modified bar gets a display:none and is hidden. There is no history icon at the top of the page
**What should have happened instead?**:
The last-modified bar should remain visible, as it is the only way for mobile users without AMC to reach the page history.
# TODO
There is no class on the body tag, to represent a diff page, so rather than resort to CSS, make sure `.last-modified-bar` is not outputted on pages which are diff page.s
