Repro Steps:

1) Create a Page
2) Equip the Path Tool (P), and draw a Path inside the Page's RootGrid.
3) Navigate to the Animation Panel (Ctrl+5), and create a new Storyboard

3) Select the Path created in Step 2), then navigate to its RenderTransform Properties, and make any adjustment to Translate, Rotate, Scale, or Skew.
At this point, a Keyframe should appear in the timeline on the first frame.

4) Advance the playhead to any position after the first frame (for example, the 1s mark), and hover over the 'Render Transform' category header in the Properties Panel (See attached image).
A 3-Dot Menu icon should now be visible.

5) Click on the Render Transform category's 3-Dot Menu, and select 'Create Keyframe'.

Observe how no results have been produced on-Stage.

Expected Results: Selecting 'Create Keyframe' on a Transform Category header produces a Keyframe across all Transform Subtypes simultaneously at their current value.

For example, clicking on 'Create Keyframe' within the Render Transform 3-Dot Menu should key, at the Playhead position in the timeline:
x1 Translate X Value
x1 Translate Y Value
x1 Angle Value
x1 ScaleX Value
x1 ScaleY Value
x1 AngleX Value
x1 AngleY Value
x1 Origin Value
