Dashboard 2 not handling item sizing or custom labels as expected

[Steve-Mcl]

@kocherjj

With {{payload}} in the 'Label' field, none of my Dash v2 buttons show msg.payload as the label, but instead show the literal string '{{payload}}'

This is not possible yet - see related post made just recently: Specify key for ui-text - #2 by Steve-Mcl
