4.17 Preview: Advanced Details Default Value Revert gets cleared when switchting movability

Reproduction steps

  1. Place a point light, directional light, box trigger, or something else in the scene (these 3 actors is what I tested )
  2. Activate “Show All Advanced Details” in the Details Panel
  3. Find such a detail and change it. For example “Shadow Bias”, “Shadow Filter Sharpen” for lights, or “Render in Mono” for the box trigger
  4. Switch their actor mobility to something else, for example from stationary to movable
  5. Observe that the yellow return/revert arrow behind this setting is removed, now assuming that the user-changed value is the default value for that variable.

This is a regression from 4.16

Changed some advanced settings results in yellow icon:


but after changing mobility results in those values getting accepted as default values:
