@Mooeypoo Tested it in beta - every time I click on back browser button on RC page with enabled filters I see type header as XHR. With not enabled RC filters, browsers back/forward buttons work as expected.

It doesn't go back to the previous page for you when you click the back button?

@Mooeypoo It doesn't. I repeated (in different browsers and different users) the exact scenario described in the ticket: the landing page is Main page, then from left navigation go to Recent changes - and then click Back browser button. RC page reloads.

Forward browser button works.

I can't reproduce this - it works perfectly for me on master and in Beta in Chrome.

Can you verify you're hard-reloading/refreshing ? This is weird...

It worked for me too locally when testing Moriel's change; I'll look again on beta in a bit.

WFM in beta in both Chrome and Firefox

It works! When I was testing previously I got an impression that the fix was not quite "trickled down" yet.

QA Recommendation: Resolve

Selecting the number of edits or days for the event list at recent changes with this beta feature enabled does not work for me now (Chrome). Can anyone confirm this bug, and could it be caused by this fix?

@Njardarlogar: Works for me on https://en.wiktionary.org/wiki/Special:RecentChanges changing to last 500 entries in Chromium 58. Please check with [[ https://www.mediawiki.org/wiki/Help:Locating_broken_scripts | safemode ]] on and feel free to file a separate task with steps to reproduce by following https://mediawiki.org/wiki/How_to_report_a_bug - thanks.

@Njardarlogar, I'm seeing the bug you mention. I've filed a new ticket for it, T167551
