Problem with searching in Numista coin list

I have some problem with searching in Numista coin list https://en.numista.com/catalogue/toutes_pieces.php?ct=coin
I press Ctrl+F, enter some word or number, and receive coincidences from all, even not expanded sections.
So, after entering something like "den", I can receive about 15000 results.
I have checked it in Google Chrome and Microsoft Edge.
I think the was some changing in the page`s code, because it used to work properly before January or December.
Thanks.

Same search:

Chrome 15,182 hits
Edge 15,182 hits
Firefox 138 hits

Hello,

There has been no change on this page, but web browsers recently changed their behaviour: see https://chromestatus.com/feature/5032469667512320

The page with all the coin is extremely heavy. I'd rather suggest using the search form of Numista.

Thanks.
Maybe I can give an advice how to turn it off?
