Comment (by rickiwylder):

 I've recently experienced this too. Trying to paste an Active Campaign
 form embed into the HTML block. The embed is one part style, one part html
 markup and the last part is a script tag where all validation logic etc is
 happening.

 This code:

 {{{
 if (elem.type != 'radio' && elem.type != 'checkbox')
 }}}

 Becomes:

 {{{
 if (elem.type != 'radio' && elem.type != 'checkbox')
 }}}


 which breaks the script. Sounds like what @ninetyninew reported although
 I'm using a custom classic theme.
