Not sure what you're doing wrong but it is displaying bech32 addresses perfectly fine for me on Chrome: LINK
Edit : now its normal on my laptop
Looks like right when I found this trick, they added official support now, or at least im showing the bech32 addresses and im not enabling the advanced view mode thing next to the txid.
Well at least I discovered it shows spents and unspent outputs if you enable that, which is useful.
But notice that if you try to click on the addresses, they will not show up. If you want to do that, you'll have to use another explorer, for example:
