Pressing Cancel after ColorPicking a Sequencer's tracked Color will not reverted the color to the previous value

Pressing Cancel after ColorPicking a Sequencer's tracked Color will not reverted the color to the previous value.
There's a bug when ColorPicking a color that is being tracked in Sequencer - pressing Cancel will initially reset the color back to it's previous value, but scrubbing the Sequencer timeline makes the discarded color be immediately applied.
For the reproduction steps I've suggested using a PointLight, but it might behave the same whenever we change a tracked color property.
I've reproduced this issue in UE5.6 and 5.7 (CL43620315).
I've included the call stack for FColorStructCustomization::OnColorPickerCancelled, although there's no reported error message in the logs.

Create a new blank project
Create a new Empty Level
Add a PointLight to the scene
Add a Level Sequence - this opens the Sequencer window
Drag the scene PointLight from the Outliner into the Sequencer window - this tracks the PointLight and exposes the LightColor property
On the Details Panel, click on the LightColor color to open up the ColorPicker
Click and drag to change the color from the default white to any color you want - this will display the new color in the small bar on the LightColor track in the open Sequencer window
Press Cancel in the ColorPicker window - this will reset the color on the LightColor bar
Grab the Playback handle and move it
Notice how the color of the bar now is back to the color you picked, before pressing Cancel on the ColorPicker window

Expected result: Pressing Cancel would reset the selection back to the original color
Actual result: Although the bar initially reset its colors, the last color selected before canceling is still saved and is applied
