@yurishkuro I have migrated the component from class to function. But in the test, there are two tests. particularly

• attempts to focus the filter input when the component updates
• throws Error when attempting to clear when required

which I am not able to convert; currently both are commented, and I am trying to fix them. other tests that required migration have been migrated.

Do we have a way of testing this in the UI?
