* Maybe this is what we need to do?
* Undo change to keyword
Use the on_html translation in the view, but pass 'on' as a keyword to
the template.
* remove unused translation
Since we only want to use views.articles.crossposted.on.html (and this is only used in the
article show template) - remove the unused 'on' key from the
translations file.
* Add a spec
Tested that this fails in main and passes on the branch
* Check that the original publication date is shown in the users local
And that it's not a <time> tag presented as text
* Correct local date selection error
If time zone was UTC (i.e. offset from utc was 0) the check for
positive? was false, I meant "non-negative" (positive or zero). Invert
the test.
