CurveEditor: keyframe not deleted properly

Keyframes are not deleted, unless I click the background area in CurveEditor. Please see attached recording.

Steps to reproduce:

• Add timeline and animate e.g position of a rectangle
• Open CurveEditor
• Click to choose property x
• Click any keyframe to choose it
• Right click and choose "Delete selected keyframes"
• -> keyframe disappears in CurveEditor as expected, but it's still visible in timeline view
• Click property y in CurveEditor and then x again
• -> deleted keyframe is back
• Try deleting a keyframe again. Now click somewhere in background area after choosing "Delete selected keyframes", and keyframe is deleted properly.
