The Inspector updates animated curves feedback (red text) inconsistently.

Sometimes, the update happens when the mouse hovers over the Inspector window
Sometimes, the update happens when the current time (timeline) is changed

The Inspector feedback "should" update as soon as a property is added or removed.

repro:
Create a Cube
Create a Clip in the Animation window
Click Add Properties... and add properties to the clip
(update issues)
Right-click on existing properties... and remove properties from the clip
(update issues)
