click() doesn't invoke tap listener on a disabled element

[dmitryxcom]

JS:

Polymer({
  is: 'x-foo',
  properties: {
    disabled: {
      type: Boolean,
      reflectToAttribute: true,
    },                  
  },
  listeners: {
    'tap': 'onTap',
  },
  onTap: () => {
    console.log('clicked!');
  }
});

html:

  <x-foo></x-foo>
  <x-foo disabled></x-foo>

in v1:

normal.click() // tapHandler is called
disabled.click() // tapHandler is caller

in v2:

$normal.click() // tap Handler is called
$disabled.click() // tapHandler is *NOT* called

probably related to #4685 and #5128

Yep, #5128 didn't check that only some elements should respond to disabled attribute. Specifically, <button>, <command>, <fieldset>, <input>, <keygen>, <optgroup>, <option>, <select>, and <textarea>

Fixed by #5230 in 2.x and #5232 in 3.x
