Steps to reproduce the issue

1. Open the test data page with Smart search module
2. Check the source code

Expected result

The input field should have an ID attribute so that browsers and assistive technologies recognize the label for this field.

Actual result

There is a "Search" label for the input field in the Smart Search module. The label can only be visible for screen readers. Unfortunately, the attribute for the label refers to an ID that does not exist because the input field does not have an ID attribute.
Note When option "Search Field Label" is set to "Show", the label is visible, but is not associated with the input field.
Chrome and Firefox browsers show in the Accessibility tree that the item has an accessible name, NVDA screen reader announces this name, but testing tools (Audits in Chrome, tota11y, ANDI) report no label.
