Comment (by poena):

 I can reproduce this with WordPress 5.7.2 (no plugins active), but
 inconsistently. Sometimes, there is no error.

 With no block style applied, I sometimes run into this JavaScript error:
 {{{

 If I add the style either before or after turning it into a reusable
 block, I am seeing the following
 JavaScript error:

 {{{
