```auto
[{"id":"51ea8e42.9005c","type":"comment","z":"3cd40fb9.7975d","name":"hasOwnProperty","info":"","x":510,"y":620,"wires":[]},{"id":"fedb34cd.f530b8","type":"comment","z":"3cd40fb9.7975d","name":"hasOwnProperty()","info":"","x":730,"y":620,"wires":[]}]

```

This may be due to the fact that `hasOwnProperty` is a defined JS method name, but a quick look has not turned up any other cases. Please don't ask how I stumbled on this.

Nick, does that also fix entering the comment ` __proto__ `.

I found that particular comment causes an array of issues e.g.

- after OKing the comment and clicking elsewhere, you cant get into the quick add popup (CTRL+Click),
- you cant delete the comment.
- Sometimes cannot get into any nodes UI
- And this is in the console log...

Yes - it prevents all prototype pollution of the internal text dimension cache.
