Opening the Inspector breaks the Y-dimension drag of Keyframes in the Keyframe Editor

[TremensS]

Tested with Kairos 2.0.2-preview + vvvv Gamma 6.7 preview-0136

Steps to reproduce:

• open the "HowTo Use Keyframe Editor extension" help patch
• open the Keyframe Editor with Ctl-F4
• in the Keyframe Editor, Keyframes can at this point be dragged in time (X axis) and in value (Y axis)
• open Inspector with Ctl-I
• in the Keyframe Editor, dragging Keyframes is constrained along the X axis (we can only change their timestamp but not their value)

I didn't find a way to recover normal behavior (including by closing the Inspector)
