add click by button title

[gimler]

Make it possible to click on a button by title. For example when you have a form button with only a font icon

<button type="submit" class="btn btn-default" title="save">
  <i class="fa fa-save"></i>
</button>

Hey, good idea.
Is the title a valid attribute for button?

@DavertMik yes, see https://www.w3schools.com/tags/tag_button.asp -> "Global Attributes" -> https://www.w3schools.com/tags/ref_standardattributes.asp

Thanks, however some tests are failing. I will restart the build on CI but maybe you will need to look at it.
Please try to fix
