I’ve catched this error in console. It appears when I translate the page with the browser built-in Google Translator.
Uncaught DOMException: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.
I changed Discourse language to e.g. French and translate it with built-in Google Translator to English.
Without Google Translate no error appears but when I turn on Google translator, after the first topic page change on New & Unread Topics the page will completely froze (broke).
I show it with topic page change but this issue also appears other pages…e.g. on
/about when changing between
/tos etc. with navigation if Google Translate enabled.
