You can also use the promisingly named 'reflectToAttribute' like this:
properties: {
value: {
type: Number,
value: 0,
notify: true,
reflectToAttribute: true
},
},
Seems like it might do the trick. Unfortunately it causes a double update,
as I clink increment it goes 1,2 2,2 3,2 4,2. Possibly Elm is rebuilding
the DOM and setting it back to 2 each time, so perhaps Html.Keyed.node is
required here.
