It is not that that the text can't be selected, the selection background color and color are not set properly. We used to set wrong CSS Variables, but In Chrome and Safari these values fallback to the defaults, whereas in FF, they become unset and there is no visual response when you press CTR+A or CMD+A.

Fix has been merged, but you have to wait for 1/2 weeks to be released in npm.
