Opening new tab from search result toggles truncatable

[ybnd]

Describe the bug
Opening an Item page in a new tab from a <ds-item-search-result-list-element> can toggle its <ds-truncatable> component

To Reproduce
Steps to reproduce the behavior:

1. Open demo7.dspace.org/search and look for an Item with a truncated description
2. Open the Item's page in a new tab ~ Right click > Open in new tab on the title link
   • Behaves as expected
3. Open the Item's page in a new tab ~ Middle click or Ctrl/Cmd + Left click on the title link
   • The page opens in a new tab, but the <ds-truncatable> component is toggled at the same time

Expected behavior
The the <ds-truncatable> component should not get toggled when clicking on the title

Thanks for reporting @ybnd . That said, this seems extremely minor to me (and unlikely to be encountered frequently)...but we may want to fix at some point. For now, putting this into 7.2

Closing, as this was fixed by #1619 / #1551 and the fix was included in 7.3
