Steps to replicate the issue (include links if applicable):

Transclude an event list that includes a comma separated filter such as :

{{Special:AllEvents
|wpFilterWikis=arwiki,dewiki,enwiki
|wpFilterTopics=fashion,tv-and-film,technology
}}

Click on Explore more events and communities

What happens?:

The filter options do not carry over to Special:AllEvents

What should have happened instead?:
The filters should be applied to Special:AllEvents when clicking on Explore more events and communities in the transcluded page

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
1.44.0-alpha (c392cae)

Here is an example to use for reproducing

also, note that |wpOpenSections=upcoming,ongoing DOES correctly convey to Special:AllEvents
