## Description
After the [Action selector redesign
PR](https://github.com/appsmithorg/appsmith/pull/21582) was merged into
release. Due to some newly added global styles, the existing CSS was
broken at few places. This PR ensures the styles added for action
selector are scoped only inside the action selector popup to avoid
globally applying those styles.
Fixes#22210

Fix for the originally reported issue. See the linked issue above.
