Description

Describe the issue

Related: https://github.com/kestra-io/kestra-ee/issues/7483

  • Flow Level Outputs display invalid expression, despite it not being selected. Doesn't do this for Variables or Inputs.
    • It displays {{ outputs.myname }} but should be {{ execution.outputs.myname }} where it's flow level
  • UI freezes when you select one of the values (Variables, Inputs, Flow Outputs, Trigger). UI box is highlighted but never stops being highlighted even when other things selected.
  • UI doesn't put that expression in the render box when selected.

Research direction
Investigate the expression rendering component in the execution overview. Check the logic for selecting Variables, Inputs, Flow Outputs, Trigger and ensure correct expressions are inserted into the render box. Also address UI freeze when selection is highlighted.
