1924082 - Add helper to lazy load custom elements

Status: RESOLVED FIXED

(Thunderbird :: Mail Window Front End, task)

Description

[Martin Giger [:freaktechnik]]

While we try to explicitly load custom elements whenever possible, sometimes that is just more complicated than necessary. To avoid loading elements unless they're needed in those situations I'd like to introduce a simple helper function that leverages customElements.setElementCreationCallback.
