Description

When enabling "Run Construction Script in Sequencer" on a Blueprint Child Actor and having "Rerun Construction Scripts" turned on in Sequencer, the Child BP's properties become inaccessible in Sequencer.

This was reported and tested in 4.22.3 (CL-7053642). This was reproduced in 4.23 (CL-8386587) and 4.24 (CL-9551884)

Steps to Reproduce
  1. Open the UE4 Editor and create a Third Person project
  2. Create a new blueprint actor
  3. Add a Skeletal mesh component to it and set it as mannequin
  4. Create two child blueprints of the created Actor
  5. In the class settings of one of the child blueprints enable Run Construction Script in Sequencer
  6. Create a level sequence, add a track for both actors, and in both add a sub track for their skeletal mesh component.
  7. In the playback settings enable the Rerun Construction Scripts option

Results: The skeletal mesh component of the blueprint with Run Construction Script in Sequencer enabled turns yellow/red and its properties become inaccessible.

Expected: The properties of the skeletal mesh component are accessible.
