 Hi!  Forgive me if this bug is a duplicate or if I need to add more info;
 first time reporting!  Also, please let me know if this is the wrong
 place.

 Using the beta editor on Safari 16.3 on an M1-based MacBook Air running on
 Ventura 13.2.1, there is a substantial slowdown to the browser tab when
 searching for a block type to add: it takes a lengthy bit of time for the
 letters to all appear, and then any search results are slow to come in and
 have the images load.

 There doesn't appear to be anything suspicious in the console, but I'm not
 sure specifically what is powering the new editor so I'm not too sure
 where to look.  I'm not running any ad blocker that might result in an
 improperly blocked failed call (although my network does run AdGuardHome)

 So far I've tested with Firefox on both Linux (nixOS; unsure of the
 Firefox version) and the Mac (110.0.1) and the comparison is night and
 day; it's lighting fast in FireFox on both browsers.

 Unsure if it's a webkit issue or whether any custom theme would be a
 problem here.  If it's a duplicate or if I can provide more information
 please let me know!
