Fix flaky boards spec due to popover

What does this MR do and why?

The popover interferes with the spec as it can steal cursor focus while the test is trying to hover over some elements.

See sample failure screenshot:

Resolves gitlab-org/quality/engineering-productivity/master-broken-incidents#6365 (closed)

The fix is similar to !152026 (merged). This popover is going to be removed in this milestone so the creation of these callout records in specs is temporary.
