NR5: trigger event when opening the documentation popover

[gregorius]

Hi There,

I noticed, by doing RED.events.DEBUG = true in the browser that this action:

does not trigger an event. It would nice - since this feature is being introduced with NR5 - to have an event triggered so that custom hooks can be added (in this case adding some JS to make the grey button work).

Just an idea ...

Worked around with

        let workspaceChangedCallback = () => {
            setTimeout(() => {
                $('.red-ui-flow-node-docs g').on('click', () => { 
                    setTimeout(activateTranscriptButton, 300) 
                })
            }, 500)
        }

        RED.events.on("workspace:change", workspaceChangedCallback)

so no need for an extra event.
