I see the error Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node popping up in sentry from time to time. I have yet to reproduce it when I try, but I know it freezes the whole UI when it happens.

It is not a very viable solution to tell users to uninstall various chrome extensions and/or not use google translate in order to not break a glimmer app. This has occurred both on Chrome and Edge.

Is it possible with a more resilient handling in clearElement?

glimmer-vm/packages/@glimmer/util/lib/dom.ts

Lines 4 to 12 in 4f1bef0

export function clearElement(parent: SimpleElement) {
let current: Option<SimpleNode> = parent.firstChild;
while (current) {
let next = current.nextSibling;
parent.removeChild(current);
current = next;
}
}

Perhaps a try-catch? Or will that disturb some other inner workings?
