Tested URL

Steps to Reproduce

1. Open the "Home page" navigate to "Assets" link in header section and activate it.
2. Navigate to "ITSM" link and activate it.
3. Navigate the columns and hover on it.
4. Observe that tooltip is inaccessible using keyboard. 

Actual Results

The tooltip content such as "Waiting for customer This was auto generated by Jira Services Management during workflow import", "Sorted Shortest -> Longest", etc. (that becomes available when user hover on table columns, "Waiting for support", etc.) elements are not accessible using keyboard. As a result, keyboard-only users will not be able to access the mentioned tooltip content effectively.

Expected Results

Apply the following changes:

• Modify scripts to make the tooltip information available on hover as well as on focus. In addition along with mouse specific event handlers, use keyboard specific event handlers, such as "onfocus", "onblur"and so on to make the functionality accessible for keyboard-only users.
• Specify the ARIA role "tooltip" for the information displayed on hover. Specify an unique "id" attribute for the tooltip and reference it via the "aria-describedby" attribute of the tooltip image or table columns.
