Now published on live wikidata: https://www.wikidata.org/w/index.php?title=Q17339402&tour=wbreferences

I'm going to be bold and go ahead with updating the Guided Tours library to the new version I made on test.wikidata. I'm rushing it through as the finding GLAMs Challenge starts tomorrow and there are 5 new tours ready to be added that won't work correctly with the current version of the tours library.
The currently live 'items' and 'statements' tours also have serious issues that will resolve with the update.

@Mrjohncummings test version ready: Test tour: https://test.wikidata.org/w/index.php?title=Q211911&tour=wbadminterritory

@Mrjohncummings ready for testing: https://test.wikidata.org/w/index.php?title=Q211911&tour=wbofficialwebsite

@Mrjohncummings this is also done on test.wikidata now: https://test.wikidata.org/w/index.php?title=Q211911&tour=wbinceptiondates

@Mrjohncummings this one is ready now as well (https://test.wikidata.org/w/index.php?title=Q211911&tour=wbimages). Post any comments here if you spot any issues. Nearly done with the last few in the 'done' column on the todo list now. I'll start moving everything over to live shortly so we can test them with all the templates and references showing correctly (only works once we move out of test.wikidata.org)

@Mrjohncummings this tour is now ready on test wikidata (https://test.wikidata.org/w/index.php?title=Q211911&tour=wbreferences2). I had to fix a few things with the slide order and headings in the wiki text, so if you want to carry on editing that make sure to do it from my test version (https://test.wikidata.org/wiki/User:NavinoEvans/tours/references)

Hi all, I think I've managed to combine the best of both versions and fix most of the outstanding issues I was planning to report.

Yes that is indeed true @Lea_Lacroix_WMDE, I just wanted to make sure everyone was aware of the issue and check for any objections to copying over the new version. My hope is that we can then organise a git repository that everyone can contribute to avoid all the difficulty tracking what versions are where, but that will be another ticket ;)

Thanks for that, yes I'm sure that must be it. My first quick attempt has not worked but will wait to see the outcome of T244994: Wikidata tours: Reconcile versions of MediaWiki:Guidedtour-lib.js before digging in any further as we should probably work from the later version of the library at https://test.wikidata.org/wiki/MediaWiki:Guidedtour-lib2.js

Note: I've updated the description as I've discovered the cause of this issue is the MutationObserver fix attempted previously. Really we have to resolve T244994: Wikidata tours: Reconcile versions of MediaWiki:Guidedtour-lib.js before we proceed with anything. If we switch to the newer version by @Rosalie_WMDE then this issue is not present.

@Mrjohncummings I've found a more or less complete tour for references waiting to go on test Wikidata - https://test.wikidata.org/w/index.php?title=Q1027&tour=wbreferences
