Bug report

Reproduction of the problem

(bug report only)
The clear button in the ComboBox (MultiColumnComboBox, etc.) currently renders as a span element and has the following attributes:

<span class="k-clear-value" role="button" tabindex="-1" title="Clear">
  ...
</span>

Excluding a button from the Tab key sequence does not hide it from a screen reader user. A screen reader user navigating by virtual cursor (using arrow keys or "next button" shortcuts) can and will still find this span element. When they arrive at it, they will hear "Clear, button." Naturally, they will press Enter or Space to activate it.

Current behavior

(optional)
Provide additional information if the steps for reproducing the faulty behavior are not sufficient to describe the issue.

Expected/desired behavior

Make the span WCAG 4.1.2 compliant: https://www.w3.org/WAI/standards-guidelines/act/rules/97a4e1/

<span 
  class="k-clear-value" 
  role="button" 
  tabindex="-1" 
  aria-label="Clear selection"
  title="Clear">
  ...
</span>

We can also consider completely hiding the span from screen readers, by rendering aria-hidden="true" on the span element, for example: 

<span 
  class="k-clear-value" 
  role="button" 
  tabindex="-1" 
  aria-hidden="true">
</span>

The Kendo Angular ComboBox implements a similar approach. This will be in accordance with WCAG 4.1.2, because aria-hidden="true" removes the element from the accessibility tree entirely, it is no longer parsed as an active UI component by screen readers.
