- Prevents the addPortletLinkHandler function from looping
over the same links multiple times by indexing
the HTMLElement instead of just the ID, which is an
optional parameter.
- Conditionally adds the icon class if the ID parameter
exists.
- Refactors the function to calculate the width of the
vector toolbar.
- Adds Jest tests to account for the dual icon scenario
and updates existing Jest tests.
