Ensure YAML editor gets updated during action change / deletion

[spacegaier]

Breaking change

Proposed change

When an action row is in YAML editor mode, it previously did not react to action changes, e.g. when one row was deleted, the editor now needed to display another YAML content. With this PR, the YAML editor gets made aware of the new content to be be shown.
