Tool doesn't work correctly when using in page move summary

[urbanecm]

Hi all,
I've noticed this perfect tool doesn't work when using a hashtag in page move summary, see https://tools.wmflabs.org/hashtags/search/d%C3%A1rek?lang=cs as example. Page WP:Článek týdne/Návrhy/Firefly (seriál) was moved with hashtag (diff https://cs.wikipedia.org/w/index.php?title=Wikipedie:%C4%8Cl%C3%A1nek_t%C3%BDdne/2016/52&diff=14486305&oldid=14262627) but tool displayed newest diff at the main page (displayed diff https://cs.wikipedia.org/wiki/?diff=0&oldid=0). Can this be fixed please?

Thanks in advance,
