Thanks for the report! This is a regression that seems to have been caused by the recent update from React 16 => 18 in #20 if I'm not mistaken.

I'll try to fix it, if @gaearon has an idea what might be wrong, I would appreciate any help.

I’ll have a look now.

I'm sorry, this is my mistake. Here is a fix. #29
