       Should filter out value in embedded mode:
     CypressError: Timed out retrying after 60050ms: `cy.click()` failed because this element is detached from the DOM.

`<button class="euiButtonEmpty euiButtonEmpty--primary euiButtonEmpty--small" type="button" aria-label="Filter out value: 0" data-test-subj="filterOutValue">...</button>`

Cypress requires elements be attached in the DOM to interact with them.

The previous command that ran was:

  > `cy.find()`

This DOM element likely became detached somewhere between the previous and current command.

Common situations why this happens:
  - Your JS framework re-rendered asynchronously
  - Your app code reacted to an event firing and removed the element

You typically need to re-query for the element or add 'guards' which delay Cypress from running new commands.

After some debugging we realize if adding 2000ms wait before the click, test would pass consistently suggesting the element needs time to load in https://github.com/opensearch-project/opensearch-dashboards-functional-test/blob/d486264c185825729f60a1e135b01a9c12c29eed/cypress/integration/core-opensearch-dashboards/opensearch-dashboards/apps/vis_type_table/embed.spec.js

We need some proper way to fix this permanently as well as other similar cases.

Thanks.

Before certain stuck we can clearly see there uncaught exceptions:

Instead of waits, I think we should try changing these to should('be.visible') in the cy.tbClickFilterFromExpand helper before executing the clicks.

Also this applies to all the tests in this file that come into the Dom after the page has loaded

Apparently this PR is missed in backports, thus showing all these errors here:
