Fix stacked plot child selection (#6275)

* Fix selections for different scenarios

* Ensure plot selection in stacked plots works when there are no selected or found annotations

* Adds e2e test for stacked plot selection and fixes the old e2e test which was testing overlay plots instead.

* Fix selection of plots while in Edit mode

* Improve tests for stacked plots

* refactor: remove unnecessary `await`s

* a11y: move aria-label to StackedPlotItem

* refactor(e2e): combine like tests, unique object names

- Use unique object names in `text=` selectors

- Combine like tests to reduce execution time

- Use `getByRole` selectors where able

* docs(e2e): add comments to test

* fix: add class back for unit test selector
