Found when checking T156697: "Days" and "limit" links on RC page need AJAX

There is a link, e.g. Show new changes starting from 21:50, 3 March 2017

<span class="rclistfrom"><a href="/w/index.php?title=Special:RecentChanges&amp;from=20170303221259" title="Special:RecentChanges" data-params="{&quot;from&quot;:&quot;20170303221259&quot;}" data-keys="from" class="mw-rcfilters-staticfilters-selected">Show new changes starting from 22:12, 3 March 2017</a></span>

When it clicked it gives -https://en.wikipedia.beta.wmflabs.org/wiki/Special:RecentChanges?hideliu=0&hideanons=0&userExpLevel=all&hidemyself=0&hidebyothers=0&hidebots=1&hidehumans=0&hideminor=0&hidemajor=0&hidepageedits=0&hidenewpages=0&hidecategorization=1&hidelog=0&from=20170303221259

The UI:

However, when the link clicked to be opened in a different tab ( or clicked on the RC page without filters)

• the url is different: https://en.wikipedia.beta.wmflabs.org/w/index.php?title=Special:RecentChanges&from=20170303220946&hidecategorization=1
• the UI will have an additional text informing users that the link was clicked and also, if the selection of specific number of records was made to be displayed - "Below are the changes since 3 March 2017, 22:12 (up to 200 shown)." In the screenshot below the message is in the red rectangle:

Note
Current production (enwiki) displays "Below are the changes since..." on the new RC page (with filters)
