Marketo Forms 2.0 datepicker/polyfill bug w/multiple forms
Just discovered another bug in Marketo forms when there's more than one form on the same page.
Symptoms: seemingly random behavior in loading the datepicker (or any other polyfill) in browsers that lack native support.
For example, Firefox does not support the native HTML <input type="date">, so the Forms 2.0 library loads a custom, JavaScript-based picker plugin (script-driven emulations of native features are called polyfills).
